The whole aim of the Buddhist way of life is to make sure that we are not again subjected to birth, or to becoming. The only way to make sure that we do not become is to cease all craving and clinging to this life right here and now. The only way to stop all suffering is to stop all becoming. The way to stop all becoming is to stop all ego aspirations here and now. That is, stop all craving and clinging.
Death is easy.
Being reborn in a new form in a new world is not easy. If we do not live this life in the right way, we will be reborn again. The Noble Eightfold Path, as taught by the Buddha, is the way to live this life in such a way as not to be reborn again, in any form, in any world. Pure freedom of the spirit is my total urge, always. Greed is ridiculous.
