The Lord... Everything is not material. That is sac-cid-ānanda-vigraha [Bs. 5.1]. Kṛṣṇa is sac-cid-ānanda-vigraha. His form is eternity, blissful and full of knowledge. So all His paraphernalia in the Goloka Vṛndāvana, that is His expansion of that quality, eternity, blissfulness and knowledge. Ānanda-cinmaya-rasa-pratibhāvitābhis. His gopīs, His consorts, His father, His mother, His friends, His trees, His flowers, His calves and cows—everything is spiritual, expansion from Him. Everything... The... We are also expansion from Him. We are marginal potency. And this is spiritual potency. So everything is expansion. Therefore the Vedic literatures say, sarvaṁ khalv idaṁ brahma: "Everything is Brahman." We are now combination of two energies, marginal energy and the external energy. But in the spiritual world, everything is only spiritual energy. So we are constitutionally spiritual energy. Somehow or other we have been entangled with this material energy. So if we try in this human form of life, we can get out of this material energy and again go back to the spiritual energy. That is the opportunity. Ānanda-cinmaya-rasa-pratibhāvitābhis tābhir ya eva nija-rūpatayā kalābhiḥ [Bs. 5.37].
