Excerpt from "The Essence of the Bhagavad Gita"

Page 163, "To drive a dark mood out of the mind, for example, try this simple method: Focus your energy and attention strongly at the point between the eyebrows. The magnetism you generate there will life you out of the fogs of gloom to a higher, more spiritual atmosphere where peace, joy and complete acceptance reign.
Again, if sex temptation assails you, bring the energy up from the lower chakras (especially from the swadisthana, or sacral) to the heart by breathing deeply a few times. Then sit still, as has been suggested above, and focus deeply on the Kutastha between the eyebrows."
