Mysticism: to dwell on the unseen, to withdraw ourselves from the things of sense into communion with God — to endeavour to partake of the Divine nature; that is, of Holiness. When we ask ourselves only what is right, or what is the will of God (the same question), then we may truly be said to live in His light.

Mysticism is the art of the practice of divine union. It is the soul's endeavor to draw nearer to God. Mysticism is the path of the heart, the path of love, the path of reverence into the citadel of enlightenment.

Mysticism is the realisation of God, of the Universal Self. It is attained either as a realisation of God outside the Mystic, or within himself. In the first case, it is usually reached from within a religion, by exceptionally intense love and devotion, accompanied by purity of life, for only "the pure in heart shall see God".

Mysticism may be defined as the attempt to realise the presence of the living God in the soul and in nature, or, more generally, as the attempt to realise, in thought and feeling, the immanence of the temporal in the eternal, and of the eternal in the temporal.

Mysticism is the art of union with Reality. The mystic is a person who has attained that union in greater or less degree; or who aims at and believes in such attainment.

Mysticism is the search for and recovery of our oneness with God.

Miracles in mysticism don't occupy such an important place. It's metaphor, for the peasants, for the crowds, to impress people. 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. You plunge into it. Philosophy is a slow process of logic and logical discourse: A bringing B bringing C and so forth. In mysticism you can jump from A to Z. But the ultimate objective is the same. It's knowledge. It's truth.

Mysticism is, in essence, little more than a certain intensity and depth of feeling in regard to what is believed about the universe.

No word in our language — not even "Socialism"— has been employed more loosely than "Mysticism." … The history of the word begins in close connexion with the Greek mysteries. A mystic is one who has been, or is being, initiated into some esoteric knowledge of Divine things, about which he must keep his mouth shut…

The phase of thought or feeling which we call Mysticism has its origin in that which is the raw material of all religion, and perhaps of all philosophy and art as well, namely, that dim consciousness of the beyond, which is part of our nature as human beings. Men have given different names to these "obstinate questionings of sense and outward things." We may call them, if we will, a sort of higher instinct, perhaps an anticipation of the evolutionary process; or an extension of the frontier of consciousness; or, in religious language, the voice of God speaking to us. Mysticism arises when we try to bring this higher consciousness into relation with the other contents of our minds.

In point of fact there are two kinds sorts of mysticism, differing from one another as the ranting of drunkards from the language of illumined spirits. There is the muddled, stammering mysticism, and there is the mysticism luminous with truly ultimate ideas. On the one hand there are the empty dimness and darkness, the barren, chilling sentimentalism and mental debauchery, the foolishly grimacing but rigid phantasms of the Cabbala, of occultism, mysteriosophy and theosophy. We cannot draw too sharp a dividing line between these and the brightness, the simple sincerity, and healthy, rejuvenating strength of genuine mysticism, which takes the most precious gems from philosophy's treasure chest and displays them in the beauty of its own setting. Mysticism is in complete accord with the result, with the sum of philosophy. In fact, mysticism is precisely the sum and the soul of philosophy, in the form of that rapturous, passionate outpouring of love.... We are concerned with an understanding of this serious mysticism, and its meaning could be stated in three words... godlessness... freedom from the world... blessedness of soul.

a mystic is someone who “perceives” life through the eyes of the soul, who experiences the power of God rather than speaks or debates the politics of God,

'Mysticism' here means, in the literal sense, a change of sensory impressions and organ sensations into something unreal and beyond this world.

In mysticism, everything is thrown at us directly, without discursiveness and ratiocination, as if it were a matter of course, and we are challenged to follow an unrestrainable will to love, arising out of a tremendously agitated, indiscriminate feeling. … Mystics will—rather than know—their thoughts. … Mysticism witnesses nothing but love; mysticism is nothing but love. … Art shows how it loves, philosophy what it loves; mysticism knows only that it loves.
