The one expansion is that īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). He has expanded Himself to live with you within your heart. Īśvaraḥ sarva-bhūtānām. Not only that; another place it is described, eko 'py asau racayituṁ jagad-aṇḍa-koṭi (Bs. 5.35). One portion of the Lord... That is confirmed in the Bhagavad-gītā: ekāṁśena sthito jagat (BG 10.42). Jagat means this material world. That is being maintained by one of His plenary portions, which is called Paramātmā, or Garbhodakaśayī Viṣṇu, or Kṣīrodakaśāyī Viṣṇu.
So one portion of His plenary portion, He is within the material world. A material world means within the universe. Aṇḍāntara-stham. Aṇḍa, brahmāṇḍa, means this universe. This is not only one universe, but there are many millions of universes. So He's there. Advaitam acyutam anādim ananta-rūpam (Bs. 5.33). And aṇḍāntara-stham: He is within the universe. Aṇḍāntara-stha-paramāṇu-cayāntara-stham (Bs. 5.35): and He is within the atom also. Just, just imagine expansion of God. So advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣaṁ nava-yauvanaṁ ca. Although He's the oldest of all, you'll find Kṛṣṇa always a young man. He's, from His face, we'll find a young boy, twenty to twenty-five years. Nava-yauvanaṁ ca. Vedeṣu durlabham. If you want to search out God by studying Vedas, it will be very difficult. Adurlabham ātma-bhaktau. But He's very easily available from His devotee. This is the description.
Then, in another place,
- ānanda-cinmaya-rasa-pratibhāvitābhis
- tābhir ya eva nija-rūpatayā kalābhiḥ
- goloka eva nivasaty akhilātma-bhūto...
- (Bs. 5.37)
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).
Another śloka is to explain: aṅgāni yasya sakalendriya-vṛtti-manti (Bs. 5.32). The spiritual body is equally qualified for doing everything. Just like with our hand, we can touch only. We cannot do... Or we can pick up something. But by simply having hand, or with the hand, we cannot eat. For eating we shall have to use this mouth, we have to use the stomach. But in the spiritual world Kṛṣṇa, about Him is described, aṅgāni yasya sakalendriya-vṛtti-manti (Bs. 5.32). Each and every limb of Kṛṣṇa has got the potency of other limbs. He can eat by His eyes. He can hear from His eyes. And anything, all the parts of the limbs, because they are spiritual, you can use it for any purpose. This is not understandable in this material condition of life, but it is possible. When it is spiritually realized, it is possible. These things are there.
