Krsna is within your heart. If you kindly continue to hear about Him, as you are doing, then Krsna will be very much pleased, “Oh, this person is now interested in me.” Because nobody’s interested in Krsna. So Krsna is also silent to them. But as soon as you become interested, oh, Krsna becomes very active, “Oh, he’s trying to do something. I shall help him.”
