Not to be contrarian, but I would note that Buddhism is atheistic. The Buddha correctly discerned that the existence or non-existence of such beings as the Hindus call ‘gods’ is of no consequence for our moral and spiritual life, but, without the light of divine revelation, did not discern the existence of the one transcendent God. Buddhism contains many consolations for the grieving, without being theistic.
Now most Western atheists are also antagonistic to mind-body dualism and the existence of a soul which continues to exist after death. It is this error that renders them incapable of consoling the grieving, not their folly in saying there is no God.
Such as?
