After health through yoga's prana, there is health through kundalini.
In reality, this varies from person to person, and some people are born with kundalini already active, making it difficult to distinguish it from prana energy.
However, based on general consensus, kundalini is initially considered inactive. Indeed, the majority of people have kundalini that is not initially active, but that does not mean that everyone has kundalini that is inactive from the beginning.
For people whose kundalini is active, there are various reasons, such as having lived a virtuous life in a past life, or being a being of a higher order who has reincarnated. In cases where kundalini is not active from birth, the sushumna, an energy channel that runs along the spine, is blocked, preventing energy from flowing through it.
To activate kundalini, it is necessary to first purify the sushumna. In reality, this is quite difficult. As I mentioned before, in my case, my spirit cleaned the impurities in my sushumna, which had been stuck there across time and space, thereby activating kundalini.
If I had not done this, I would have likely remained in a state where kundalini was not active for another 10 years or more. In my case, I have had out-of-body experiences several times since childhood, even reaching a state that could be considered a future life, and I realized that if I did not clean my sushumna at that timing, it would stagnate. Therefore, I cleaned my sushumna for my future self.
In reality, what initially happened was not the sushumna itself, but two lines of light rising. This was likely the awakening of ida and pingala. Ida and pingala are energy channels that exist on the left and right of the sushumna. The general consensus is that they are spiral-shaped, but in my case, they were straight.
Kundalini initially begins with a state where the entire body becomes warm and revitalized. However, as it settles down, it first becomes dominant in the manipura chakra, and then gradually shifts to the anahata chakra, slowly rising. As the dominant chakra rises, changes occur in the mind, and it becomes more stable psychologically. As it rises, it becomes less susceptible to negative influences, and therefore, it becomes more positive, and the expression also becomes better. In addition, the body becomes more active, and physical health improves.
In this way, the Kundalini energy and a positive lifestyle can lead to a feeling of lightness in the body, and generally, one can live a healthy life both physically and mentally.
