In the next stage, under the guidance of the spiritual master, the devotee executes regulative devotional service, and as a result of such activities, he becomes freed from all unwanted occupations. When he is freed from unwanted occupations, his faith becomes steadily fixed, and he develops a transcendental taste for devotional service, then attachment, then ecstasies, and in the last stage there is pure love of Godhead. These are the different stages of the development of pure love.
Only the most fortunate persons can achieve such success in life. Those who are simply academic students of the Vedic scriptures cannot appreciate how such a development takes place. In the Nārada-pañcarātra Lord Śiva therefore tells Pārvatī, "My dear supreme goddess, you may know from me that any person who has developed the ecstasy of love for the Supreme Personality of Godhead, and who is always merged in transcendental bliss on account of this love, cannot even perceive the material distress or happiness coming from the body or mind."
