na vidanty api yogeśā
yoga-māyāṁ kuto vayam
Systematic understanding of something should include knowledge of both its svarūpa, or essential identity, and also its viśeṣas, the attributes that make it different from other things. Māyā, the energy underlying all material existence, is more subtle than ordinary phenomena. Only God and His liberated devotees, therefore, can know its svarūpa and viśeṣa.
