There are two lives, the natural and the spiritual, and we must lose the one before we can participate in the other. - William James

Be willing to have it so. Acceptance of what has happened is the first step to overcoming the consequences of any misfortune.

Plasticity … means the possession of a structure weak enough to yield to an influence, but strong enough not to yield all at once. Each relatively stable phase of equilibrium in such a structure is marked by what we may call a new set of habits. Organic matters, especially nervous tissues, seem to be endowed with a very extraordinary degree of plasticity of this sort ...

To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one has already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our DIS-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of its possessor's body at the time.
