So, sometimes a parent takes the baby and then throws the baby up in the air, and they go, *gasps*, and he catches, or sometimes in the water they hold the baby in hand, and all of a sudden let the hand go, “Daddy!” (devotees laughing), so they’re forced to depend a little more on the parents, or something, but actually the parent is all along, holding the child. Sometimes the situation happens where it seems that, “Well, why there’s so much difficulty?” But, actually, in the eternal sequence it’s just for a flash, but during that moment, that’s actually the opportunity for us to really depend upon Krishna and realize that He’s actually the one who is making or breaking us. He’s the one who is actually the ultimate controller. Because our tendency is to depend simply upon our own material intelligence, simply upon our material abilities, simply upon so many material situations, not that a devotee doesn’t use intelligence, and use everything, but the actual dependence on success or failure is left to Krishna.
