Sri Swami Sivananda

desire stimulates a thought; a thought embodies itself as an act. Act constitutes the web of destiny.

sow an action and reap a habit; a habit sown results in character. You sow a character and reap a destiny.

Mind is the subtle form of this physical body. The physical body is the outward manifestation of the thoughts. So when the mind is wrought, the body is wrought too.
