Baatin is a term that originates from Arabic, meaning "inner" or "hidden." It is often used in various spiritual and philosophical contexts to refer to the deeper, esoteric meanings of texts or experiences, contrasting with the outward or literal interpretations, known as Zahir. In Islamic mysticism, particularly within Sufism, Baatin represents the inner dimension of faith and understanding. Practitioners seek to uncover these hidden truths through meditation, reflection, and guidance from spiritual leaders, emphasizing the importance of personal experience in grasping the essence of their beliefs.
