Sri Aurobindo's Conversations with Pavitra. Part 6. The Force Descends

Pavitra: I can at times keep my attention fixed, "turned upwards" (pointed towards Sahasrara) and my mind calm and empty of thought. But all is closed up there — I am at the door and knock. Something curious happened this morning. I woke up with waves of powerful vibrations at the top of the head and in the pit of the stomach. They were even physical, my scalp was sensitivised. These vibrations were connected with a sort of anguish — though I was not frightened and reproduced these vibrations in order to study them.
