When you are focused in the third eye, just imagine that the essence of prana is showering from the top of the head, just as if you are sitting under a tree and flowers are showering, or you are just under the sky and suddenly a cloud begins to shower, or you are just sitting in the morning and the sun rises and rays begin to shower. Imagine, and immediately there is a shower - a shower of light falling down from the top of your head. This shower recreates you, gives you a new birth. You are reborn.
