Pranayama is the fourth limb o Ashtanga Yoga. 'Prana' is the life force, ayama means control.
Breathe and Mind are very much related to each other. When one is controlled the other is automatically controlled.
This fact is discovered by our ancient adepts and revealed for the benefit of mankind-
When one does Pranayama regularly, certain psychic powers are also developed in him.
Prana is not mere breathe. It is the power behind breathe. Prana is the subtle energy pervading in the whole Universe.
Light, electricity and magnetic force are all manifestations of this Prana.
Features of Pranayama:-
1) Slowing of breath rate, uniformity, continuity and rhythm.
2) Equalization of breathe between 2 nostrils.
3) Breathe-awareness--3D awareness
The Richest thing in this World that even the Poorest man is gifted with is this "PRANA".
The Pity is that the value of PRANA IS least known!
