Another exercise I'm confused about in the Perfect Matrimony is the exercise that goes: the devotee puts his thumbs in his ears, closes his eyes and seals them with the his index fingers, closes the nose with the middle fingers, and finally, seals the lips with the ring and little fingers. Under these conditions the student must try to see the tattvas with the sixth sense. This eye is found between the eyebrows.
My question is, how do I breathe!!
