We men have one book in common which points to God. Each has it within himself, which is the priceless Name of God. Its letters are the flames of His love, which He out of His heart in the priceless Name of Jesus has revealed in us. Read these letters in your hearts and spirits and you have books enough. All the writings of the children of God direct you unto that one book, for therein lie all the treasures of wisdom. … This book is Christ in you.
–Jacob Boehme, Explaining his symbol of the Tetragrammaton within the human heart, in Libri Apologetici (1730), Book I, as quoted in The Secret Teachings of All Ages (1928) by Manly P. Hall, “The Human Body in Symbolism”; courtesy of Wikiquote.
The most powerful prayer, one wellnigh omnipotent, and the worthiest work of all is the outcome of a quiet mind. The quieter it is the more powerful, the worthier, the deeper, the more telling and more perfect the prayer is. To the quiet mind all things are possible. What is a quiet mind? A quiet mind is one which nothing weighs on, nothing worries, which, free from ties and from all self-seeking, is wholly merged into the will of God and dead to its own.
–Meister Eckhart, as translated in A Dazzling Darkness: An Anthology of Western Mysticism (1985) by Patrick Grant; courtesy of Wikiquote
What is the Sufi’s belief regarding the coming of a World Teacher, or, as some speak if it, the “Second Coming of Christ?” The Sufi is free from beliefs and disbeliefs, and yet gives every liberty to people to have their own opinion. There is no doubt that if an individual or a multitude believe that a teacher or a reformer will come, he will surely come to them. Similarly, in the case of those who do not believe that any teacher or reformer will come, to them he will not come. To those who expect the Teacher to be a man, a man will bring the message; to those who expect the Teacher to be a woman, a woman must deliver it. To those who call on God, God comes. To those who knock at the door of Satan, Satan answers. There is an answer to every call. To a Sufi the Teacher is never absent, whether he comes in one form or in a thousand forms he is always one to him, and the same One he recognizes to be in all, and all Teachers he sees in his one Teacher alone. For a Sufi, the self within, the self without, the kingdom of the earth, the kingdom of heaven, the whole being is his teacher, and his every moment is engaged in acquiring knowledge. For some, the Teacher has already come and gone, for others the Teacher may still come, but for a Sufi the Teacher has always been and will remain with him forever.
