Understand the microcosm and the macrocosm.
Understand the original sound.
Understand the mahapralaya.
Understand the undifferentiated energy in its pure state.
The ultimate reality.
The root of the universe.
Aum...Aum...Aum...
All the fuss about yoga, meditation, music and prayers is to help our way back to the primordial nadhabrahmam from where everything evolved.
Way back to absolute peace - the nothing and everything.
