THE FOUR SAMPRADAYS (SB 7.9.18) | HG SREESHA GOVIND DAS

In the Padma Purāṇa it is said, sampradāya-vihīnā ye mantrās te niṣphalā matāḥ. There are four sampradāyas, or disciplic successions, which are authorized for delivering transcendental knowledge . If one wants to advance in spiritual power, one must receive his mantras from one of these bona fide sampradāyas; otherwise he will never successfully advance in spiritual life.

All of the four original sampradāyas are still scrupulously engaged in the transcendental service of the Lord up to date, and they all declare that Lord Kṛṣṇa, Mukunda, is the Supreme Personality of Godhead, and no other personality is equal to Him or greater than Him.

Let us understand:

What are these four sampradāyas ?

What are their common teachings ?

Who are the prominent Acharaya of these sampradāyas ?
