For the one who is moderate in eating, recreation, working, sleeping, and waking, this yoga [of meditation] destroys [all] sorrow.

Living in solitude, eating lightly, controlling the thought, word, and deed; ever absorbed in yoga of meditation, and taking refuge in detachment.

In Karma-yoga no effort is ever lost, and there is no harm. Even a little practice of this discipline protects one from great fear [of birth and death].

The state of severance of union with sorrow is known by the name of yoga.

Yoga is difficult for the one whose mind is not subdued.

Karma-yoga is a supreme secret indeed.
