Although the equations are usually made: Islamic esotericism = Sufism, and Judaic esotericism = Kabbalah; this is not always correct. To refer to all Islamic esotericism as "Sufism" is like referring to all modern unconventional non-materialistic and non-mainstream religious ideas as "New Age". Just as there are unconventional ideas that are neither non-materialistic, mainstream religious, or "New Age", so there are forms of esotericism within the Islamic world that are not the same as, or even related to, "Sufism".
