Spiritual body in magical philosophy is the highest aspect of the human individual. It is the essence, or the divine spark, or the soul forming the core of each person and exists eternally. The conscious awareness of this spiritual body, or having it reflected through the ordinary self into the surrounding environment, is considered the highest level of magical attainment, and brings with it the total mastery of powers and potentials of the self.
