Purity is absolutely the basic work, the bed-rock upon which the whole Bhakti-building rests. Cleansing the external body and discriminating the food are both easy, but without internal cleanliness and purity, these external observances are of no value whatsoever. In the list of qualities conducive to purity, as given by Ramanuja, there are enumerated, Satya, truthfulness; Ârjava, sincerity; Dayâ, doing good to others without any gain to one's self; Ahimsâ, not injuring others by thought, word, or deed; Anabhidhyâ, not coveting others' goods, not thinking vain thoughts, and not brooding over injuries received from another. In this list, the one idea that deserves special notice is Ahimsa, non-injury to others. This duty of non-injury is, so to speak, obligatory on us in relation to all beings.
The test of Ahimsa is absence of jealousy. Any man may do a good deed or make a good gift on the spur of the moment or under the pressure of some superstition or priestcraft; but the real lover of mankind is he who is jealous of none. The so-called great men of the world may all be seen to become jealous of each other for a small name, for a little fame, and for a few bits of gold. So long as this jealousy exists in a heart, it is far away from the perfection of Ahimsa.
The man whose heart never cherishes even the thought of injury to any one, who rejoices at the prosperity of even his greatest enemy, that man is the Bhakta, he is the Yogi, he is the Guru of all (III, 67-68)
