Just as in earthly life lovers long for the moment when they are able to breathe forth their love for each other, to let their souls blend in a soft whisper, so the mystic longs for the moment when in prayer he can, as it were, creep into God.
What does mysticism really mean? It means the way to attain knowledge. It’s close to philosophy, except in philosophy you go horizontally while in mysticism you go vertically.
All mystics speak the same language, for they come from the same country
There is only one religion, though there are a hundred versions of it.
He who would be serene and pure needs but one thing, detachment
To be full of things is to be empty of God. To be empty of things is to be full of God
The knower and the known are one. Simple people imagine that they should see God as if he stood there and they here. This is not so. God and I, we are one in knowledge
Anger and intolerance are the twin enemies of correct understanding
It is better to conquer yourself than to win a thousand battles. Then the victory is yours. It cannot be taken from you, not by angels or by demons, heaven or hell
We have all read in scientific books, and, indeed, in all romances, the story of the man who has forgotten his name. This man walks about the streets and can see and appreciate everything; only he cannot remember who he is. Well, every man is that man in the story. Every man has forgotten who he is. One may understand the cosmos, but never the ego; the self more distant than any star. Thou shalt love the Lord thy God; but thou shalt not know thyself. We are all under the same mental calamity; we have all forgotten our names. We have all forgotten what we really are. All that we call common sense and rationality and practicality and positivism only means that for certain dead levels of our life we forget that we have forgotten. All that we call spirit and art and ecstasy only means that for one awful instant we remember that we forget.
– G. K. Chesterton (Orthodoxy)
