A Karma-yogi performs action by body, mind, intellect, and senses, without attachment (or ego), only for self-purification.

The power of God is with you at all times; through the activities of mind, senses, breathing, and emotions; and is constantly doing all the work using you as a mere instrument.

One gradually attains tranquillity of mind by keeping the mind fully absorbed in the Self by means of a well-trained intellect, and thinking of nothing else.

With senses, mind, and intellect under control; having liberation as the prime goal; free from lust, anger, and fear; such a sage is verily liberated.

Earth, water, fire, air, ether, mind, intelligence and false ego-all together these eight contitute my separted material energies

A person is said to have achieved yoga, the union with the Self, when the perfectly disciplined mind gets freedom from all desires, and becomes absorbed in the Self alone.
