Ahaituki, without any cause. “O Lord, I love You, God, because You supply me so many nice things. You are order-supplier.” No. Not that sort of love. Without any exchange.

That is taught by Caitanya Mahaprabhu, that “Whatever You do…” Aslisya va pada-ratam pinastu mam [Cc Antya 20.47].

Either You trample Me under Your feet or You embrace Me… What You like. You make Me brokenhearted by not seeing You — that doesn’t matter. Still You are My worshipable Lord.” That is love. “From God’s side, He may do whatever He likes. I don’t want anything in exchange.” That is love. That sort of love Krsna wants.

Therefore He was so much fond of the gopis. In the gopis’ love there was no question of business propaganda — “Give me this, then I love You.” [chuckles] No. That is pure love. That is unalloyed love. Ahaituky apratihata. Apratihata means without being checked. No impediment. If you want to love God, there is nothing throughout the whole world which can check you. Simply you have to develop your eagerness: “Krsna, I want You.” That’s all. Then there is no question of checking. In any condition you’ll increase your love, increase your love. Ahaituky apra…

And why this? Yayatma suprasidati. If you attain that state, then you will feel fully satisfied. Otherwise not. Otherwise not. If you can develop your love for God, or Krsna, without being checked, without any cause, then you will feel fully satisfied. Otherwise not. It is for your interest. It is not for God’s interest that He wants you. It is for your interest. If you do otherwise, you will never be happy. This is the only way. Sarva-dharman parityajya mam ekam saranam.
