I am That
The supreme shakti, whose nature is to create, constantly expresses herself upward in the form of exhalation, and downward in the form of inhalation. By steadily fixing the mind on either of the two spaces between the breaths, one experiences the state of fullness of Bhairava.

The Science of Hamsa
Hamsa is the natural Mantra, linked to the life-force of every living being. It is literally the sound of our breathing. To understand Hamsa is to become aware of our unity with the cosmos. Its secret is revealed in the Upanishads, in the writings of the great masters, and above all, in the great tantric treatise, the Vijnana Bhairava. Commenting on this text, Swami Muktananda explains the technique and philosophy of this simple mysterious awareness.
