When Annamalai Swami went to Bhagavan for help to control his sexual desires.

Bhagavan:
Why should you always be thinking that an evil thought occurred at such and such a time in the past? If you instead meditate "To whom does this thought come?" it will fly away of its own accord. You are not the body or the mind, your are the Self. Meditate on this and all your desires will leave you.
