How Can Something Not Be Krishna

“Everything has a cause, and that cause or seed of manifestation is Krishna. Without Krishna's energy, nothing can exist; therefore He is called omnipotent. Without His potency, neither the movable nor the unmovable can exist. Whatever existence is not founded on the energy of Krishna is called maya, that which is not.” (Shrila Prabhupada, Bhagavad-gita, 10.39 Purport)
