Quite the opposite effect is desired for one who is moving towards conscious union with the Infinite, the Unbounded, the Ascendant. Stillness of the breath is a natural and effortless consequence of your deep experience of the Ascendant. Forcing the breath into a semblance of stillness is decidedly not a method of inducing deep experience of the Ascendant. That's like putting the cart before the horse. Rather, the result of your experiences of the Ascendant is that the breath stills, easily and naturally.
Humanity is like seeds planted in the soil of earthly experience.
We become so involved in the darkness that most of us have forgotten that light ever existed. But we each have the perfect pattern of our most expanded Self within. Through Ascending, this perfection grows and we naturally begin to totally let go of the husk of our limited beliefs about who and what we are. We become willing to stretch beyond our self-created boundaries. By Ascending, we trust in a greater light than our limited self.
