Yoga and the Master of Yoga
3
You may want Kṛṣṇa as your lover, as your son; you may want Kṛṣṇa as your friend, you may want Kṛṣṇa as your master, you may want Kṛṣṇa as the Supreme Sublime. These five different kinds of direct relationship with Kṛṣṇa are called devotion, or  bhakti . They entail no material profit.

This is the costasy of extreme love. There is such a relationship between Kṛṣṇa and His devotee Rādhārāṇī, the greatest devotee, the greatest lover of Kṛṣṇa. Mother Yaśodā is His lover as a
