When reading the following passage from Swami Muktananda's "Satsang with Baba, Volume III" (August 18, 1972, page 122), I thought that it was another explanation of the mechanics of stress release; that is, that the thoughts we have during meditation are indications of stress being released on the physical level:
"According to the seers of the yogic scriptures, countless impressions of past lives are embedded in the central nadi, sushumna. After Kundalini becomes awake, these impressions start rising to the surface. You should be aware that they are coming to the surface to be ejected from the system. If you are aware of this truth, you will find it entirely pointless to be concerned or overwhelmed by the feelings that come to the conscious surface."
