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.

That Religion is not devotion, but work and suffering for the love of God; this is the true doctrine of Mystics — as is more particularly set forth in a definition of the 16th century: "True religion is to have no other will but God's." Compare this with the definition of Religion in Johnson's Dictionary: "Virtue founded upon reverence of God and expectation of future rewards and punishments"; in other words on respect and self-interest, not love. Imagine the religion which inspired the life of Christ "founded" on the motives given by Dr. Johnson! Christ Himself was the first true Mystic. "My meat is to do the will of Him that sent me and to finish His work." What is this but putting in fervent and the most striking words the foundation of all real Mystical Religion? — which is that for all our actions, all our words, all our thoughts, the food upon which they are to live and have their being is to be the indwelling presence of God, the union with God; that is, with the Spirit of Goodness and Wisdom.

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 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 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.

Thus we see that mysticism naturally, though not necessarily, becomes intimately associated with whatever is the religion of the culture in which it appears.

We shall start from the assumption that a mystic, insofar as he participates actively in the religious life of a community, does not act in the void. It is sometimes said, to be sure, that mystics, with their personal striving for transcendence, live outside of and above the historical level, that their experience is unrelated to historical experience. Some admire this ahistorical orientation, others condemn it as a fundamental weakness of mys­ticism. Be that as it may, what is of interest to the history of reli­gions is the mystic's impact on the historical world, his conflict with the religious life of his day and with his community. No his­torian can say — nor is it his business to answer such questions­ whether a given mystic in the course of his individual religious experience actually found what he was so eagerly looking for. What concerns us here is not the mystic's inner fulfillment. But if we wish to understand the specific tension that often prevailed between mysticism and religious authority, we shall do well to recall certain basic facts concerning mysticism. A mystic is a man who has been favored with an immediate, and to him real, experience of the divine, of ultimate reality, or who at least strives to attain such experience. His experience may come to him through sudden illumination, or it may be the result of long and often elaborate preparations. From a historical point of view, the mystical quest for the divine takes place almost exclusively wit a prescribed tradition-the exceptions seem to be limited to modern times, with their dissolution of all traditional ties. Where such a tradition prevails, a religious authority, established long before the mystic was born, has been recognized by the com­ munity for many generations.

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.

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.

What deserves to be called mysticism—not in the vague sense of the history and philosophy of religion, but rather in the Catholic-ecclesial sense—occurs when God's Word is heard, not only with exegetical and theological understanding, but with the whole heart, the whole being, when one is steadfast before the self-disclosure of the heart of God despite fire and night.

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.

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.

Gödel shared with Einstein a certain mystical turn of thought. The word “mystic” is almost pejorative these days. But mysticism does not really have anything to do with incense or encounter groups or demoniac possession. There is a difference between mysticism and occultism.
A pure strand of classical mysticism runs from Plato to Plotinus and Eckhart to such great modern thinkers as Aldous Huxley and D. T. Suzuki. The central teaching of mysticism is this: Reality is One. The practice of mysticism consists in finding ways to experience this higher unity directly.
The One has variously been called the Good, God, the Cosmos, the Mind, the Void, or (perhaps most neutrally) the Absolute. No door in the labyrinthine castle of science opens directly onto the Absolute. But if one understands the maze well enough, it is possible to jump out of the system and experience the Absolute for oneself.

If Christian mysticism and its goal, ecstasy, is the contact of man with God through a leap from human nature to divine nature, national mysticism is nothing other than the contact of man and crowds with the soul of their race through the leap which these forces make from the world of personal and material interests into the outer world of race. Not through the mind, since this anyone can do, but by living with their soul.
