Krishna explained to Yashoda the reason why He preferred butter in Gopikas’ homes, to the butter offered by her. The hearts of Gopikas were pure and filled with selfless devotion to Krishna. Their devotion was superior to the maternal affection of Yashoda, which bore a taint of selfishness. Krishna told Yashoda: “I am attracted to the hearts of those who are pure and selfless.” Krishna always eluded Gopikas after playing His mischief. But once, out of compassion for them, He wanted to provide a clue by which they could trace Him. One day they all lay in wait around their houses to catch Krishna. Krishna went into a house stealthily, broke a pot of milk and quietly hid Himself. Gopikas found that He had broken the pot, and they tried to trace Him. The milk-white steps which He left revealed to them His hide-out. Then, Krishna revealed to them the spiritual truth that, if they cling to the feet of the Lord, they will realise Him. “Follow My footsteps and you shall find Me,” Krishna told Gopikas! – Divine Discourse, Sep 04, 1996.
