You may ask yourself.
Many people know the thirty-six times be suitable, as asserted in many scriptures and canons.
Yet, this assertion in reality doesn't mean the number of breathing but the number with which you can reckon the necessary number of times in consideration of all your deficiency of congenital nature, the constitution, the extent of development of the emerging vita-vapor and so forth. It is by no means an easy thing for a man not expert at the Book of Changes, to know the necessary number. Later you are advised to resume the motionless state to recede again into the emptiness and stillness of the heart. Be patient enough to wait for the motion out of the infinite stillness again, and to prepare again for the subsequent running of small water-wheel. Yet many men have the notion that the fertilizing fluid could be accumulated for the use of constituting the golden elixir.
