"Reshape yourself through the power of your will; never let yourself be degraded by self-will. The will is the only friend of the Self, and the will is the only enemy of the Self. To those who have conquered themselves, the will is a friend. But it is the enemy of those who have not found the Self within them"
- Bhagavad Gita, the Indian epic
