It even believes that in a more or less spiritual manner your very body will survive.

It essentially clings to the ego.
What it inculcates is really present endeavor sanctioned by the prospect of future bliss.

It tacitly takes for granted the desirability of personal existence, and promises the certainty of personal immortality,--a terror to evildoers, and a sustaining sense of coming unalloyed happiness to the good.

Through and through its teachings runs the feeling of the fullness of life, that desire which will not die, that wish of the soul which beats its wings against its earthly casement in its longing for expansion beyond the narrow confines of threescore years and ten.
Buddhism, on the contrary, is the cri du coeur of pessimism.

This life, it says, is but a chain of sorrows.
