In Sanskrit this highest stage is called premā, premā can be defined as love of God without any expectation of exchange or return. Actually the words premā and love are not synonymous, yet one can say that premā is the highest stage of love. One who has attained premā is the most perfect human being. Śrīmad-Bhāgavatam also confirms this statement (SB 3.25.25): Only by the association of pure devotees can one develop a taste for Kṛṣṇa consciousness, and when he tries to apply Kṛṣṇa consciousness in his life, he can achieve everything up to the stage of bhāva and prema.
Lord Caitanya, describing the symptoms of a person who has developed from faith to the stage of bhāva, states that such a person is never agitated even if there are causes for agitation. Nor does such a person waste his time even for a moment; he is always anxious to do something for Kṛṣṇa. Even if he has no engagement, he will find some work to do for Kṛṣṇa's satisfaction. Nor does such a person like anything which is not connected with Kṛṣṇa. Although he is situated in the best position, he does not hanker after honor or personal respect. He is confident in his work, and he is never under the impression that he is not making progress toward the supreme goal of life-going back to Godhead. Since he is fully convinced of his progress, he is always confident and keeps himself busy to achieve the highest goal. He is very much attached to gratifying the Lord and in chanting or hearing about the Lord, and he is always attached to describing the transcendental qualities of the Lord. He also prefers to live in holy places like Mathurā, Vṛndāvana or Dvārakā. Such characteristics are visible in one who has developed to the stage of bhāva.
