Bright but hidden, the Self dwells in the heart.
Everything that moves, breathes, opens, and closes
Lives in the Self. He is the source of love
And may be known through love but not through thought.
He is the goal of life. Attain this goal!
...
In his robe are woven heaven and earth,
Mind and body. Realize him as the One
Behind the many and stop all vain talk.
He is the bridge from death to deathless life.
Where all the nerves meet like spokes in a wheel,
There he dwells, the One behind the many.
Meditate upon him in the mantram.
May he guide us from death to deathless life!
...
The Lord of Love is before and behind.
He extends to the right and to the left.
He extends above; he extends below.
There is no one here but the Lord of Love.
He alone is; in truth, he alone is.
