bhaki yoga in three steps

Srila Prabhupada in simple English explains the process of Krishma Consciousness in three steps;

1. In the beginning one must have a preliminary desire for self-realization. This will bring one to the stage of trying to associate with persons who are spiritually elevated. 
2. In the next stage, one becomes initiated by an elevated spiritual master, and under his instruction the neophyte devotee begins the process of devotional service. 
3. By execution of devotional service under the guidance of the spiritual master, one becomes freed from all material attachments, attains steadiness in self-realization and acquires a taste for hearing about the Absolute Personality of Godhead, Śrī Kṛṣṇa.
