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.
When we see beautiful thing, what is it? It is just some light entering into our eyes and it is making us mad. Some frequency entering our ear & we get mad. Something scraping our tongue which is just a lump of flesh wiggling around. But when something touches its surface we go mad. This is material enjoyment & we take it seriously.
Total absorption in playing flute for pleasure of Lord Krishna.
The moment a living entity moves his face away from Krishna, he naturally goes to sense enjoyment.
This process of chanting is the best process of self-realization in this age; therefore Lord Caitanya preached it so nicely for the benefit of all humanity.
Srimad Bhagavatam 3.24.35,
Cow protection is not just to not slaughter the cows, but to make them happy from the moment they are born till they naturally leave their bodies.
