But it is not an exaggeration to say that mystical experience is everywhere unitary in the same sense that everywhere aesthetic experience is unitary… - Walter Terence Stace

To be genuinely civilized means to be able to walk straightly and to live honorably without the props and crutches of one or another of the childish dreams which have so far supported men. That such a life is likely to be ecstatically happy I will not claim. But that it can be lived in quiet content, accepting resignedly what cannot be helped not expecting the impossible, and being thankful for small mercies, this I would maintain. That it will be difficult for men in general to learn this lesson I do not deny. But that it will be impossible I would not admit since so many have learned it already.

And we think that this ultimate blessedness differs only in degree from the happy and joyful experiences of our lives. Whereas the truth is that it differs in kind. The joys, not only of the earth, but of any conceivable heaven - which we can conceive only as some happy and fortunate prolongation of our lives in time - are not of the same order as that ultimate blessedness.

The most important, the central characteristic in which all fully developed mystical experiences agree, and which in the last analysis is definitive of them and serves to mark them off from all other kinds of experiences, is that they involve the apprehension of an ultimate nonsensuous unity in all things, a oneness or a One to which neither the sense nor the reason can penetrate.
