Purifying the Heart
One cannot get bhāva-bhakti or prema-bhakti by mere sādhana (practice). What you get is pure devotion. You can become a pure devotee by sādhana bhakti. But many times it is confused that pure devotion and prema (love) are synonymous. Before you get love of Kṛṣṇa, you have to be pure. You have to become a pure devotee.
