Here is, in truth, the whole secret of Yoga, the science of the soul. The active turnings, the strident vibrations, of selfishness, lust and hate are to be stilled by meditation, by letting heart and mind dwell in spiritual life, by lifting up the heart to the strong, silent life above, which rests in the stillness of eternal love, and needs no harsh vibration to convince it of true being.

Yoga is a practical method for making one's life purposeful, useful and noble.

Sloth is the great enemy -- the inspirer of cowardice, irresolution, self-pitying grief, and trivial, hairsplitting doubts. Sloth may also be a psychological cause of sickness. It is tempting to relax from our duties, take refuge in ill-health and hide under a nice warm blanket.

Yoga takes you into the present moment, the only place where life exists.

The Yoga of action, leading to union with the soul is fiery aspiration, spiritual reading and devotion to Ishvara.

Yoga is the practice of quieting the mind.
