Sufism is a way of love, a way of devotion, and a way of knowledge.
There is no single, systematic approach to Sufi teachings, and not all of its teachings can be communicated in words. The wisdom of Sufism can be found in stories, poetry, art, calligraphy, rituals, exercises, readings, dance movements, and prayer.
