Although one of the most attractive features of the Hare Krishna movement in the western countries especially is the revelation of the form of God, sometimes people challenge us that God cannot be seen, so why are we worshiping His form? Srila Prabhupada gives a rather simple answer here in this nice conversation with Bob Cohen and his fiancé Barbara.
Barbara: Have you ever seen Krsna?
Barbara: You have?
Prabhupada: Daily. Every moment.
Barbara: But not in the material . . . not in the material body?
Prabhupada: Huh? No in . . . he has no material body.
Barbara: Well in the temple here they have pictures of Krsna . . .
Prabhupada: That is not material. You are seeing material . . .
Prabhupada: . . . because you have got material eyes. Because your . . . you have got your material eyes, you cannot see the spiritual form. Therefore He kindly appears to be in material body so that you can see. This is the point. Because He has kindly made Himself just fit for your seeing, that does not mean He is . . . he has material body.
Just like President Nixon, if he kindly comes to your house, it does not mean that his position and your position is the same. It is his kindness, out of love, he may come to your house, but that does not mean he is on the same level with you. Similarly, because we cannot see with our present eyes what is Krsna, therefore Krsna appears before us as painting, as made of stone, as made of wood. And Krsna is not different from these paintings and wood, because everything is Krsna.
