CC Madhya 23.14-15, Translation:

" 'In the beginning there must be faith. Then one becomes interested in associating with pure devotees. Thereafter one is initiated by the spiritual master and executes the regulative principles under his orders. Thus one is freed from all unwanted habits and becomes firmly fixed in devotional service. Thereafter, one develops taste and attachment. This is the way of sādhana-bhakti, the execution of devotional service according to the regulative principles. Gradually emotions intensify, and finally there is an awakening of love. This is the gradual development of love of Godhead for the devotee interested in Kṛṣṇa consciousness.'
