"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."
