A. C. Bhaktivedanta Swami Prabhupada

Out of many millions of wandering living entities, one who is very fortunate gets an opportunity to associate with a bonafide spiritual master by the grace of Krishna. By the mercy of both Krishna and the spiritual masters, such a person receives the seed of the creeper of devotional service.

Every living creature is the son of the supreme Lord, and He does not tolerate even ants being killed

You should not be carried away by the dictation of the mind, but the mind should be carried by your dictation.
