We are being harassed by getting these different types of body and engagement according to the body. That we can understand. We are not happy. One after another. Because our main business is sense gratification. So we cannot enjoy all these senses fully in one kind of body. There is some defect. Just like we are trying to gratify our senses by flying to another planet, moon planet. This is another sense gratification. We are meant for this planet. We are bound up by conditions. Artificially we are trying to go there. And making plans, so many plans: "There will be intermediate station, and the petrol will be carried from here," and this and that.
So many things. Simply spending money. Just like childish. The child, they spoil their time and energy in certain playing. Similarly, this is going on. Because it is a sense gratification. That's all. Simply mere sense gratification: "Let us go, how it is, moon planet." You have no business there. You cannot do there anything. You cannot live there, but still, "Let us go, let us go. And spend all the money, taxpayers' money, spend like water." This is going on.
