Sri Aurobindo

If you want to be a true doer of divine works, your first aim must be to be
totally free from all desire and self-regarding ego. All your life must be an
offering and a sacrifice to the Supreme; your only object in action shall be to
serve, to receive, to fulfill, to become a manifesting instrument of the Divine
Shakti in her works.

-- Sri Aurobindo
