Nothingness 2

Hamsa Yoga Sangh:
If Earth Peace is to Herald the Dawn of the New Age, let us All Realize:
"Humanity is one's only religion
Breath one's only prayer, and
Consciousness one's only God."

.

What is nothingness? Is it the same as emptiness, the void, shunya, consciousness, the ether, the vacuum, the unmanifest, pure potentiality, pure Awareness? How is this related to bliss, enlightenment, self-realization, nirvana, samadhi, nirvikalpa samadhi, etc? Yogiraj explores this topic here.
