" Kṛṣṇa can perfectly reciprocate one’s loving propensities in different relationships called mellows, or rasas. Basically there are twelve loving relationships. One can love Kṛṣṇa as the supreme unknown, as the supreme master, the supreme friend, the supreme child, the supreme lover. These are the five basic love rasas. One can also love Kṛṣṇa indirectly in seven different relationships, which are apparently different from the five primary relationships. All in all, however, if one simply reposes his dormant loving propensity in Kṛṣṇa, then his life becomes successful. This is not a fiction but is a fact that can be realized by practical application. One can directly perceive the effects that love for Kṛṣṇa has on his life. "
