During meditation, my breathing spontaneously stops, and Kevala Kumbhaka has reappeared.

Thinking back, this happened quite a while ago, around February 2018. However, after the awakening of Ida and Pingala (Kundalini) in November of the same year, I actually became less skilled at breath retention, and it hadn't happened since then. But recently, unexpectedly, during meditation, it's happening again in the same way as before: my breathing stops for a while, although it's only about 30 seconds or so. After exhaling, I don't automatically inhale, and my breathing stops in the exhaled state. After a while, I don't feel anything unusual for a short time, but after a while, I gradually start to feel uncomfortable, so I consciously inhale. In this state, I have to consciously and explicitly inhale, otherwise, I only exhale.

This doesn't happen in my daily life, and it doesn't happen every time I meditate; it only happens occasionally.

As a meditation state, this is actually quite good. My mind is stable, and I have very few distracting thoughts. Even if I do have thoughts, they don't usually disrupt my meditation. My aura extends from the lower part of my body to the Sahasrara chakra, so I can maintain a good meditation state. However, only my breathing stops, and even though I am conscious, after a while, I judge that "this is not good for my body," so I consciously inhale.

After inhaling and taking a few conscious breaths with a consistent rhythm to properly fill my lungs, when I resume meditation, my breathing tends to be dominated by the exhale, and my inhale doesn't move automatically. Again, my breathing stops in the exhaled state.

This type of Kevala Kumbhaka is said to occur during meditation in yoga, and it is described in the Hatha Yoga Pradipika, the Shiva Samhita (3.47), the Gheranda Samhita (5.89-96), or the Yoga Sutra (2.50).

These descriptions all state that after the natural cessation of breathing due to Kevala Kumbhaka, Samadhi or the achievement of Raja Yoga is attained. In my case, since this Kevala Kumbhaka occurred before my initial Kundalini experience, it could indeed be seen as a sign of achievement. However, I think that this Kevala Kumbhaka is probably not a sign of achievement, but rather a sign that "it's time to move on to the next stage."

According to the descriptions, they all have in common the meaning of achieving a balance of internal energy.

Indeed, just before Kundalini awakens for the first time and becomes dominant in Manipura, there is a certain degree of stability in terms of energy, and although it is still limited, it can be said that there was a certain state of equilibrium. Even in that stage, where Kundalini itself, and even Ida and Pingala, are not functioning properly in a low dimension, it can still be said that it was a stable state. When that state is reached, which is a "calm state" or a "plateau" state where growth seems to have temporarily stopped, it is likely that the energy becomes stable, and therefore, Kevala Kumbhaka may occur.

As for my current state, it is relatively stable, but it has not yet opened up to Sahasrara, and although it is a certain state of equilibrium, meditation is stable, and energetically it is rich and there is no excess or deficiency, and there are no particular problems, but still, I feel that there is a wall above. That state is similar to the period before the awakening of Kundalini (mainly Ida and Pingala) in the early stages.

This state of energy equilibrium is probably not permanent, but rather a plateau-like state, and it is likely a stable state before leaping to the next stage.

However, this is just a speculation, so I will continue to meditate and observe.
