The right arm feels tingling, while the left arm feels stable. However, I haven't been very conscious of this difference because my right arm has always been weaker. I simply thought that the tingling in my right arm was stronger because energy was flowing through it. I thought that eventually, the feeling would become the same on both sides, but after a few days, it hasn't changed, and I was wondering what to do. Then, I suddenly realized that, in yoga, the energy on the left and right sides is described as Ida and Pingala, respectively. Ida is on the left and is associated with the moon, representing cool and calming energy, which is also considered feminine energy. Pingala is on the right and is associated with the sun, representing warm and active energy, which is also considered masculine energy. So, the difference in my sensations seems to be consistent with this understanding, and the tingling on the right side feels like it's a natural occurrence.

Left: Ida, Moon, Cold, Calming, Feminine
Right: Pingala, Sun, Warm, Active, Masculine

According to some theories, Kundalini energy is generated by Ida and Pingala, and I can definitely feel that.

This state seems to indicate that both Ida and Pingala are relatively activated. In my case, the Ida on the left side already had a certain amount of energy, and now it's flowing properly. The Pingala on the right side was originally weak, but recently it has been quite active, so the balance between the two sides is relatively good.

In this state, the central Sushumna channel is relatively well connected along the spine, from the sacrum to the heart chakra (Anahata). However, the throat chakra (Vishuddha) seems a bit constricted, and while it is connected to the head, the Vishuddha chakra seems to be the bottleneck. The Vishuddha chakra feels a bit weak, but overall, it seems to be connected to the Ajna chakra in the head.

In this state, I can feel that multiple energies are connected to the Ajna chakra, which is located between the eyebrows. The shape of the Ajna chakra feels like a flower with petals that are open to the left and right. I can definitely feel that there are multiple pathways connected to both Ida and Pingala. There is a common understanding about the number of energy pathways connected to the chakras, and it is said that the Ajna chakra is the confluence of Sushumna, Ida, and Pingala, which aligns with my experience.

In reality, the left and right channels, referred to as Ida and Pingala, are not just one channel each, but rather consist of multiple channels, such as those that pass through the front of the cheek, those that pass along the outside of the cheek, and those that pass through the inside of the body. It is difficult to distinguish which of these is Ida and which is Pingala, and there are differences in notation depending on the text in the Indian Upanishads, so my (tentative) interpretation is that these several channels that are divided into the left and right are collectively referred to as Ida and Pingala.

▪️Energy also flows through the legs.

In addition, by firmly channeling energy through the legs, the sensation reaches the fingertips. Regarding the legs, in my case, it still seems weak, and the energy does not always flow strongly, but when meditating, especially by consciously extending awareness from the base of the foot towards the toes, the energy channels (nadis) seem to be strengthened.

▪️Be aware of energy in daily life or while lying down.

If you get used to it, you can strengthen the energy channels not only during meditation but also in daily life or when you are drowsy while lying down, and it seems that it is quite effective to consciously pay attention to them occasionally when you notice them.
