from the Bhagavad Gita

He who can see inaction 
 in the midst of action, and action
in the midst of inaction,  is wise
and can act in the spirit of yoga.

With no desire for success,
no anxiety about failure,
indifferent to results, he burns up
his action in the fire of wisdom.

Surrendering all thoughts of outcome,
unperturbed, self-reliant,
he does nothing at all, even
when fully engaged in actions.

There is nothing that he expects,
nothing that he fears. Serene,
free from possessions, untainted,
acting with the body alone,

content with whatever happens,
unattached to pleasure or pain,
success or failure, he acts
and is never bound by his action.

When a man has let go of attachments,
when his mind is rooted in wisdom,
everything he does is worship
and his actions all melt away. (BG 4.19.24)
