"A devotee is always kind to everyone, even to his enemy. Nirmama means that a devotee does not attach much importance to the peace and trouble pertaining to the body because he knows perfectly well that he is not the material body. He does not identify with the body; therefore he is freed from the conception of false ego and is equipoised both in happiness and distress. He is tolerant, and he is satisfied with whatever comes by the grace of the Supreme Lord. He does not endeavor much to achieve something with great difficulty; therefore he is always joyful. He is a completely perfect mystic because he is fixed in the instructions received from the spiritual master, and because his senses are controlled, he is determined. He is not swayed by false argument because no one can lead him from the fixed determination of devotional service. He is fully conscious that Krsna is the eternal Lord, so no one can disturb him. All his qualifications enable him to depend entirely on the Supreme Lord."
(Bhagavad-gita As It Is, 12.13-14, Purport)
