A person in Kṛṣṇa consciousness who is fully devoted to the transcendental loving service of the Lord develops all the godly qualities of the demigods. There are many divine qualities, but Lord Caitanya describes only some of them to Sanātana Gosvāmī. A devotee of the Lord is always kind to everyone, and he does not pick quarrels. His interest is in the essence of life, which is spiritual. He is equal to everyone, and no one can find fault in him. His magnanimous mind is always fresh and clean and devoid of material obsessions. 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.
There is also a description of the devotee of the Lord in Śrīmad-Bhāgavatam (3.25.21) wherein he is said to be always tolerant and merciful. A friend to all living entities, he has no enemies. He is peaceful, and he possesses all good qualities. These are but a few of the characteristics of a person in Kṛṣṇa consciousness.
It is also said in Śrīmad-Bhāgavatam that if one gets an 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 transcendental, composed, peaceful, friendly to all living entities and not subject to anger. Simply by association with such holy men one can become a Kṛṣṇa conscious devotee. Indeed, to develop love of Godhead, the association of holy devotees is needed. The path of advancement in spiritual life opens for anyone who comes in contact with a holy man, and by following the path of the devotee, one is sure to develop Kṛṣṇa consciousness in full devotional service.
