First you develop love then you can surrender fully

Without love, Krishna Prema, your surrender is conditional, artificial or partial. First develop Krishna prema by chanting the Hare Krishna mahamantra. Then like Gopis you can have love which is unconditional, complete surrender. Abandon all religions and completely surrender. Even veda-dharma. They have abandoned.

But condition is there. You may chant for years together. But nothing will happen. You have to give up pride. I am so and so.

Trinad api sunicena, taror iva sahisnuna, amanina manadena, kirtaniya sada Hari.

Think oneself lower than the grass. Lowest of the low. Be tolerant as a tree. And don't expect respect. Give respect because Krishna is in their hearts - in all their hearts. If you develop such mentality, you'll be able to get Krishna prema.
