SRI KRISHNA:

He who knows bliss in the Atman
And wants nothing else.
Cravings torment the heart:
He renounces cravings.
I call him illumined.
Not shaken by adversity,
Not hankering after happiness:
Free from fear, free from anger,
Free from the things of desire.
I call him illumined.
The bonds of flesh are broken.
He is lucky, and does not rejoice:
He is unlucky, and does not weep.
I call him illumined.

The tortoise can draw in his legs:
The seer can draw in his senses.
I call him illumined.

The abstinent run away from what they desire
But carry their desires with them:
When a man enters Reality,
He leaves his desires behind him.

Even a mind that knows the path
Can be dragged from the path:
The senses are so unruly.
But he controls the senses
And recollects the mind.
And fixes it on me.
I call him illumined.
