Attahassa is not the giggle of comfort. It is the echoing, ground-shaking laugh of one who has stopped negotiating with fear.
When the Mother's presence settles in a sadhaka, the first thing that goes is the constant inner audition for approval. What remains is a strange joy, a self-love that has nothing to do with the self.
This laugh is the most subversive sound in Kali Yuga. It cannot be sold, cannot be cancelled, cannot be performed. It is the natural acoustics of being inhabited by Adya.
