Krsna is joyful. I am part and parcel of Krsna; therefore I must be also joyful. That is natural. If my father is black, then I am also black. If my mother is black, I am also black. So our father, the supreme father Krsna, is joyful. Don’t you see Krsna’s attitude? Anywhere you see, Krsna is joyful. He is not engaged in some industrial work or in some heavy machine making. He is simply playing on His flute. You see? And Radharani is there. That is joyful nature.
