Krishna is like the sun who dispels the fog of our sins.
Dayananda das : I spent a month as Prabhupada's servant prior to the '76 Mayapur festival. I had been studying Sanskrit so I knew quite a few verses. And one of my favorite verses, if not my favorite verse, is kecit kevalaya bhaktya vasudeva-parayanah, agham dhunvanti kartsnyena niharam iva bhaskarah, which means that for the unalloyed devotee Krishna dispels the sins just like the sun dispels the fog. So we were walking on the roof of Mayapur and in the morning in Mayapur, for anybody who has visited Mayapur, they've probably seen the fog that hangs over all the rice paddies. Bengal is this wonderfully lush country and Mayapur is this flat, flat country where you can see for miles, but sometimes there is this fog that lingers over the top of the rice paddies and sometimes it can be incredibly beautiful. The sun is coming up so you can see the action of the sun clearing the fog and it's just incredible, the whole scenery. So one time Prabhupada was walking on his morning walk, and he stopped and he paused and looked out over this panorama and indicated with a sweep of his hand the sun and then he said, "Kecit kevalaya bhaktya vasudeva-parayanah," the first line from this verse indicating that Krishna is like the sun who dispels the fog of our sins. It was an incredible, wonderful experience.
