■Information
The theory underlying the power of the universe has been analyzed down to its most subtle threads, and practical methods for awakening this great power within the individual are suggested. This book explains the theory and describes the practice of Kundalini Yoga.■Preface "The Experience of Kundalini Awakening"
During meditation, you see the form of God, experience God's smell, taste, touch, and hear God's Anahata sound. You receive instructions from God. This indicates that the Kundalini Shakti has awakened. When there is activity in the Muladhara. When the hair stands on end. When Uddiyana, Jalandhara, and Mula Bandha occur unconsciously. This is how you know that Kundalini has awakened.The Anahata sound is the Nada sound. Kundalini Shakti is the power of Kundalini, symbolized by the goddess. Muladhara is the root chakra. Uddiyana, Jalandhara, and Mula Bandha are three yogic bandhas, which involve fixing specific areas of the body, but they seem to occur automatically. In my case, as mentioned in the article about Nada sound, I can hear the Nada sound, and I have had one experience where the Kundalini Shakti awakened slightly. I am not sure whether the bandhas occur automatically or not.
When Kevala Kumbhaka, the involuntary cessation of breath, occurs spontaneously, you know that the Kundalini Shakti is being activated. When you feel that the Prana (subtle energy) is flowing up to the Sahasrara (crown chakra), when you experience bliss, when you automatically repeat the Om mantra, when thoughts of the world are not in your mind, you know that the Kundalini Shakti has awakened.
Kevala Kumbhaka is one of the "signs" that indicate progress in meditation. As consciousness becomes still, breathing naturally stops. This happens to me quite naturally during meditation, while lying in a recliner, or during yoga's Shavasana.
In meditation, when Shambhavi Mudra, focusing the eyes on the Trikuti, the point between the eyebrows, occurs, you know that the Kundalini is being activated. When you feel vibrations of Prana (subtle energy) in various parts of your body, when you experience a shock-like tremor, you know that the Kundalini is active. When you feel as if your body is not there during meditation, your eyelids are closed, you sweat but they do not open, and an electric-like current flows through your nerves, you know that the Kundalini has awakened.
When you receive inspiration and insights during meditation, when the nature of those insights reveals secrets to you, when all doubts disappear, and you clearly understand the meaning of the Vedic scriptures, you know that the Kundalini is invigorated. When your body feels as light as air, when you maintain a calm mind even in noisy environments, when you have an inexhaustible amount of energy for work, you know that the Kundalini is active.
When you experience ecstasy towards God, when you develop the power of oratory, you know that the Kundalini has awakened. When you perform various yoga poses with minimal pain or fatigue, unconsciously, you know that the Kundalini is being activated. When you unconsciously create beautiful and sublime hymns and poems, you know that the Kundalini is invigorated.
It seems to be based on classical texts such as Raja Yoga and Hatha Yoga Pradipika.
■A slight increase in the mind.
The chakra is the center of Shakti, which is a vital force. In other words, it is the center of prana-shakti in the body, created by pranava, and it is connected to the cosmic consciousness of the deities (Devatas), which manifest in the form of this chakra center. The chakras cannot be perceived physically. Even if the corresponding part of the body that helps to organize them is perceived, that part of the body will perish with death.The scriptures say that the sound of pranava is the sacred sound Om, but its mystery is difficult to understand. It seems to be a mystical knowledge that makes the soul and spirit manifest through pranava.
Purity of the mind leads to completion in yoga. When interacting with others, regulate your actions. Do not feel jealousy towards others. Be a compassionate person. Do not hate sinners. Be kind to everyone. If you put your maximum effort into yoga practice, the success of yoga will be rapid.
You must desire liberation and intense vairagya (detachment). You must be honest and serious. Intense and regular meditation is necessary to enter samadhi (a state of meditation).
The hearts of worldly people who have basic desires and passions are located in the Muladhara and Swadhisthana chakras, which are located near the anus and genitals, respectively. When the heart is purified, the heart rises to the Manipura chakra, which is the center of the navel, and experiences a certain amount of power and joy. When the heart is further purified, the heart rises to the Anahata chakra, which is the center of the heart, and experiences happiness, and the graceful form and guardian deity of the Ishta-Devata (ideal deity) are visualized. When the mind is highly purified, and when meditation and devotion are intensely deepened, the mind rises to the Vishuddha chakra, which is the center of the throat, and experiences even more power and joy. Even if the mind reaches this center, it may descend to the lower center.
When the yogi reaches the Ajna chakra, which is the center between the two eyebrows, he achieves samadhi and realizes Brahman, which is the ultimate self. There is a slight sense of separation between the devotee and Brahman. If the yogi reaches the Sahasrara chakra, which is the spiritual center of the brain, symbolized by a thousand lotus petals, he attains nirvikalpa samadhi, which is a state of superconsciousness. He becomes one with the non-dual Brahman. All feelings of separation dissolve. This is the highest Sampragyata Samadhi, which is the highest aspect of consciousness. Kundalini is connected to Shiva.
The yogi descends to the center of the throat and gives instructions to the disciples, and does good things for others (Lokasamgraha).
■ Pranayama to awaken Kundalini.
When practicing the following, focus on the triangular-shaped Muladhara Chakra, which is the seat of Kundalini Shakti, located at the base of the spine. Close the right nostril with the right thumb. Inhale through the left nostril, counting slowly to three "Om." Imagine that you are drawing prana from the atmosphere. Next, close the left nostril with the little finger and ring finger of the right hand. Then, hold your breath for 12 "Om." Imagine the current (prana) flowing down the spine and directly to the triangular lotus, the Muladhara Chakra. Imagine that the nerve current (prana) is hitting the lotus, and that Kundalini is awakening. Then, exhale slowly through the right nostril, counting to six "Om." Using the same units, and with the same imagination and sensation, repeat the process from the right nostril as described above. This pranayama will awaken Kundalini quickly. Practice it three times in the morning and three times in the evening. Gradually and carefully increase the numbers and times, according to your strength and ability. In this pranayama, it is important to focus on the Muladhara Chakra. The stronger the concentration, and the more regularly the pranayama is practiced, the sooner Kundalini will awaken.This is known as Anulom Vilom, a type of alternate nostril breathing.
■ Kundalini Pranayama
In this pranayama, the ratio of inhalation (prāka), breath retention (kumbhaka), and exhalation (rechaka) is less important than the intention (bhavana) held in the mind.Control of prana (life force) is emphasized more than physical control of the breath.
Sit facing east or north, in the padmasana or siddhasana posture. Mentally prostrate yourself at the lotus feet of your true guru (spiritual guide), and after reciting hymns praising God and the guru, begin this pranayama, which easily leads to the awakening of kundalini.
In the traditional Indian yoga, prayers and mantras are recited at the beginning and end of everything.
Inhale deeply, without making a sound. As you inhale, feel the kundalini, dormant in the mūlādhāra chakra, awaken and ascend through the chakras. At the end of the inhalation (prāka), hold the intention (bhavana) that the kundalini has reached the sahasrāra. The more vivid the visualization of the connection between the chakras, the faster your progress will be in this sādhanā (spiritual practice).
Hold your breath for a while. Recite the prāṇava (sacred sound Om) or the name of your ishta-deva (chosen deity). Concentrate on the sahasrāra chakra. Feel that the darkness of ignorance enveloping your soul is dissolving, thanks to the grace of the mother kundalini. Feel that everything in you is permeated by light, power, and wisdom.
Exhale slowly. As you exhale, feel the kundalini shakti gradually descending from the sahasrāra chakra, tracing each chakra, and returning to the mūlādhāra chakra.
Begin the process again. This pranayama is so wonderful that it is impossible to fully praise it. It is a magic wand that achieves perfection very quickly. Even a few days of practice will convince you with its amazing glory. Let us begin from this moment. May God bless you with joy, bliss, and immortality.
■Kundalini
The word Kundalini is familiar to all yoga practitioners. It is known as a power, and it is in the form of a coiled serpent that lies dormant in the Muladhara chakra, which is the first of the seven chakras. The other six chakras are, in order, Swadhisthana, Manipura, Anahata, Vishuddha, Ajna, and Sahasrara.All sadhana (spiritual practices), such as japa (mantra repetition), meditation, kirtan (chanting), and prayer, cultivate all virtues and the observance of austerities such as truth, non-violence, and self-control. This accumulates the power of the serpent to awaken it, and it passes through a series of chakras from Swadhisthana to Sahasrara. Sahasrara is also known as the lotus of a thousand petals, and it is said to be the seat of Sadashiva, or Parabrahman, or the Absolute, which is separated from the Kundalini Shakti that lies in the Muladhara. Eventually, the Kundalini passes through all the chakras as mentioned above, leading to integration. This integration with the Divine is what liberates the yoga practitioner, and it is the culmination of their efforts.
The Shiva who resides in Sahasrara and the Kundalini Shakti who resides in Muladhara are usually separate, and when they unite, it leads to awakening.
In the case of worldly people who enjoy sensual and sexual pleasures, this power of Kundalini remains dormant because it is not stimulated through spiritual practices. Only the power generated through such spiritual practices, and not the power gained through worldly wealth and abundance, awakens the power of the serpent (Kundalini). A spiritual guide, who holds the title of Guru, and whose Kundalini has already awakened and reached the higher chakra of Sadashiva, helps and guides others who are trying to achieve the same goal, and by following the instructions of the pioneer, the disciple practices all the disciplines that are forbidden in the scriptures, and the layers of veils surrounding the Kundalini begin to clear, and eventually tear, and the power of the serpent is pushed or moved in an upward direction.
Super-sensory visions appear in the spiritual eye of the practitioner, and a new world of indescribable wonder and charm is revealed before the yogi, and many layers successively reveal their existence and glory before the practitioner. And the yogi gains the knowledge, power, and bliss of God, which increases successively. As Kundalini passes through the chakras, the chakra blooms before Kundalini touches it. Do not let go of that power. It emits a sacred light and fragrance, and reveals the secrets and manifestations of God. It is hidden from the eyes of worldly people, and they refuse to believe in its existence.
When Kundalini ascends to one of the chakras, which is the center of the yogi, the yogi ascends one step on the ladder of yoga. Another page, the next page, he reads the book of God. As Kundalini ascends, the yogi also advances towards the goal, which is spiritual perfection. When Kundalini reaches the sixth center, the Ajna chakra, the yogi receives a vision of the personal God, Saguna Brahman, and when the power of the serpent reaches the final top center, the Sahasrara chakra, which is the lotus of ten petals, the individual personality dissolves into the ocean of Sat-Chit-Ananda (Existence-Pure Consciousness/Knowledge-Bliss), and becomes one with the Supreme Soul, the Lord. He is no longer an ordinary person, nor a simple yogi, but a perfectly radiant saint who has conquered the kingdom of infinite God, a hero who has won the battle against illusion, a liberated being (Mukta) who has transcended the ocean of ignorance or the natural existence, and a superior being who has the authority and ability to save the souls of others who are suffering in the relative world, and the scriptures praise him the most for his achievements and the path of the highest glory. Even Brahma, Vishnu, and Shiva, the three existences, the beings of heaven, envy him.
