“The particular word kṛṣṇa-devatāḥ, i.e., those who are always rapt in the service of Lord Kṛṣṇa, is significant. The Yādavas and the Pāṇḍavas, who were always rapt in the thought of the Lord Kṛṣṇa and His different transcendental activities, were all pure devotees of the Lord like Vidura. Vidura left home in order to devote himself completely to the service of the Lord, but the Pāṇḍavas and the Yādavas were always rapt in the thought of Lord Kṛṣṇa. Thus there is no difference in their pure devotional qualities. Either remaining at home or leaving home, the real qualification of a pure devotee is to become rapt in the thought of Kṛṣṇa favorably, i.e., knowing well that Lord Kṛṣṇa is the Absolute Personality of Godhead.”
