This essay examines the concept of “unity” in the work of Sri Aurobindo. This unity, according to Aurobindo, could not take place unless Man’s vital and mental nature was uplifted by a spiritual supernature. For Aurobindo, the evolutionary process of human unity is possible through yogic experience, not through rationality. In Aurobindo’s thought, every human being is a yogi, but not a conscious one. Those who have become conscious of this process through the yogic experience can help others.
