The Most Potent Formula
Service to the Vaishnavas is the most potent formula for getting the mercy of Spiritual Mater and Krishna.
Guru Kripa
Whatever our destiny is, whatever our Karma is, if we simply accept the mercy of Guru, "Guru Kripa", it can completely liberate us from all of our previous Karmic bondage.
Realization
To hear means to follow, and through this comes realization.
Coming to The Final Conclusion
To be meek and humble means to have a service attitude towards God, the Vaisnavas, and all living beings. Unless we have that, our chanting will have minimal effect and many births may pass before we finally come to the conclusion.
