As mentioned above, a person in Kṛṣṇa consciousness, being fully devoted to the transcendental loving service of the Lord, develops all the godly qualities of the demigods. There are many such qualities, but Lord Caitanya described only some of them to Sanātana Gosvāmī.
A devotee of the Lord is always kind to everyone; he does not pick quarrels. His interest is in the essence of life, which is spiritual. He is equal to everyone, no one can find fault in him, his magnanimous mind is always fresh and clean, and he is without material possessions. He is a benefactor to all living entities and is peaceful and always surrendered to Kṛṣṇa. He has no material desires. He is very humble and is fixed in his purpose. He is victorious over the six material qualities, such as lust and anger, and he does not eat more than he needs. He is always sane and is respectful to others, but he does not require respect for himself. He is grave, merciful, friendly, poetic, expert and silent.
Śrīmad-Bhāgavatam (3.25.21) also describes the person in Kṛṣṇa consciousness, one who is devoted to the loving service of the Lord. There the devotee is said to be always tolerant and merciful, and a friend to all living entities. He has no enemies, he is peaceful, and he possesses all good qualities. These are a few of the characteristics of a person in Kṛṣṇa consciousness.
It is also said in Śrīmad-Bhāgavatam (5.5.2) that if one gets the opportunity to serve a great soul—a mahātmā—his path to liberation is open. However, those who are attached to materialistic persons are on the path of darkness. Those who are actually holy are transcendentalists; they are equipoised, very peaceful, free from anger, and friendly to all living entities. Simply by association with such holy men one can become a Kṛṣṇa conscious devotee of the Lord. Indeed, to develop love of Godhead, the association of such great souls is needed. The path of advancement in spiritual life opens for anyone who comes in contact with such holy men, and by following their path, one is sure to develop Kṛṣṇa consciousness in full devotional service.
