maruto ‘ntar bahir vāpi viyadyugmānivartanāt
ā bhairavasyettham bhairavi vyajyate vapuh

Radiant one,
The life essence carries on its play
Through the pulsing rhythm
Of outward and inward movement.
This is the ceaseless throb, the rhythm of life —
Terrifying in its eternity, exquisite in its constancy.

The inhalation, the return movement of breath,
Sustains life.
The outgoing breath
Purifies life.
We breathe out the old air, thoughts, feelings.

These are the two poles
Between which respiration goes on unceasingly.
Between them is every delight you could desire.
