According to Osho, you are not punished for sin later by some external judge; you are punished by the sin itself, instantly. Sin is unconsciousness—anger, excess, hate—that burns and poisons you as you do it. Likewise, love and awareness are immediate reward, heaven-now. Responsibility is present-moment: act consciously to end suffering at its source.
When you do unkind or unaware things, they hurt you right away; kind, aware actions feel good immediately.
