Power of Chanting
One may or may not know the power of chanting the Hare Krishna mantra, but if one chants the holy name he will become free from all sinful reactions.
Srimad Bhagavatam 6.2.18,
Srila Prabhupada
Establishing Relationship With Lord Krishna
One should try to purchase a ticket to go back home, back to Godhead. The price of such a ticket is one’s intense desire for it, which is not easily awakened, even if one continually performs pious activities for thousands of lives. All mundane relationships are sure to be broken in the course of time but once one establishes a relationship with the Supreme Personality of Godhead in a particular rasa, it is never to be broken, even after the annihilation of the material world. — Sri Caitanya Caritamrita, Adi Lila, Chapter 01, Text 56.
Attainig Ecstacy
Ecstacy is only available by spiriutal indulgence. Material nature can’t give us everlasting happiness, which our heart is searching for.
Surrender and Prayers
By surrendering and praying for the causeless mercy of the Lord, the devotee can progress on the path of complete self-realization
