Anyone who has developed unalloyed, unflinching devotional service unto the Lord develops his original good qualities as spirit soul. The spirit soul, as part and parcel of the Supreme Personality of Godhead, has all the good qualities of the Lord. When the spirit soul is contaminated by the material modes of nature, one is considered good or bad with reference to the material qualities. But when one is transcendental to all material qualities, all the good qualities come out. These qualities of a devotee, twenty-six in number, are listed as follows: (1) kind to everyone, (2) does not quarrel with anyone, (3) fixed in the Absolute Truth, (4) equal to everyone, (5) faultless, (6) charitable, (7) mild, (8) clean, (9) simple, (10) benevolent, (11) peaceful, (12) completely attached to Kṛṣṇa, (13) has no material hankering, (14) meek, (15) steady, (16) self-controlled, (17) does not eat more than required, (18) sane, (19) respectful, (20) humble, (21) grave, (22) compassionate, (23) friendly, (24) poetic, (25) expert, (26) silent. The Lord is satisfied by development of the transcendental qualities of the living entity and not by artificial performance of sacrifices and mystic yoga. In other words, unless one is fully qualified to become a pure devotee of the Lord, one cannot expect to be liberated from material entanglement.
