If one concentrates on the body as a void, even for a moment, with the mind free from thought, then one attains thoughtlessness and verily becomes that form of void (known as Bhairava).
One should contemplate on the skin of the body as a mere wall or partition with nothing inside it. By meditating thus, he becomes like the void, which cannot be meditated upon.
O embodiment of good fortune, one who contemplates with closed eyes and one-pointed concentration on the mantra in the middle of the lotus in the heart space achieves the highest spiritual realization.
When the mind is dissolved in dwadashanta by steady awareness and steady practice, the true nature or essence of the goal manifests everywhere in one's body.
