Râja-Yoga is divided into eight steps. The first is Yama — non-killing, truthfulness, non-stealing, continence, and non-receiving of any gifts. Next is Niyama — cleanliness, contentment, austerity, study, and self-surrender to God. Then comes Âsana, or posture; Prânâyâma, or control of Prâna; Pratyâhâra, or restraint of the senses from their objects; Dhâranâ, or fixing the mind on a spot; Dhyâna, or meditation; and Samâdhi, or superconsciousness. The Yama and Niyama, as we see, are moral trainings; without these as the basis no practice of Yoga will succeed. As these two become established, the Yogi will begin to realise the fruits of his practice; without these it will never bear fruit. A Yogi must not think of injuring anyone, by thought, word, or deed. Mercy shall not be for men alone, but shall go beyond, and embrace the whole world.
