So here everything is duality, relative knowledge, relative world, but in the absolute world everything is one, spirit. Here... because here we have got experience two energies, spiritual energy and material energy, working. The material energies are the physical elements, bhūmir āpo 'nalo vāyuḥ: (BG 7.4) earth, water, fire, air, sky, and, in subtle form, mind, intelligence, ego. They are all material. Mind is also material, intelligence is also material, but they are subtle forms. And spiritual existence is the living entity, as we are. These things are very nicely explained in the Bhagavad-gītā. Apareyam itas tu viddhi me prakṛtiṁ parām. The material, physical elements, they are inferior quality of, inferior quality, energy, of Kṛṣṇa. But the superior quality of energy we are, living entities. Jīva-bhūtāṁ mahā-bāho yayedaṁ dhāryate jagat (BG 7.5).
Therefore here in this material world there are two energies working. In the spiritual world there is only spiritual energy working. But in the material world, two energies are working: material and spiritual. Material energy is dependent on spiritual energy. Spiritual energy is prominent everywhere, in this material world and the spiritual world. Here also, the matter is developing upon spirit, not that spirit is manifesting under certain conditional stage of matter. That is a wrong theory. For example, the small spiritual spark, the living entity, very small, we cannot even imagine with our material brain. It is one ten-thousandth part of a point. We, in the material world, we cannot measure the length and breadth of point. Therefore those who are mathematicians, they say, "Point has no length, no breadth." But actually that is not a fact. You have no eyes to see the length and breadth of a point. You are so blunt, your senses are so limited, imperfect, that you cannot imagine that a point can have length and breadth. But we get information from Vedic literature, not only the point, but one ten-thousandth part of the point is measured. Keśāgra-śata-bhāgasya śatadhā kalpitasya ca, jīvo bhāgaḥ sa vijñeyaḥ (CC Madhya 19.140). Because we have no imagination, we have no instrument, neither we have sufficient knowledge what is the length and breadth of the form of the living entity, therefore Vedic literature gives you an idea that you just try to imagine one ten-thousandth part of the point, and that is the measurement. Keśāgra-śata-bhāgasya śatadhā kalpitasya ca, jīvo bhāgaḥ sa vijñeyaḥ sa cānantyāya kalpate (CC Madhya 19.140). So living entities, spiritual spark, that measurement is given there. Whenever there is measurement, there is form. It is not...
But because we cannot see the form, we say nirākāra. It is our incompetency. Just like I cannot see beyond this wall. My seeing power is limited. Therefore I see there is nothing beyond this. There is nothing beyond this room. That is not fact. There is everything. I can see the sun, which is fourteen hundred thousand times bigger than this planet, but my eyes are seeing, daily just like a disc. So don't believe your senses. Your senses are imperfect. Whatever knowledge you get by experimental knowledge, experimental method, that is the modern ways of understanding. But these things cannot be experimented. Therefore we have to take the knowledge from the Vedas. Tad-vijñānārthaṁ sa gurum evābhigacchet samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham (MU 1.2.12). Tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti sūrayaḥ. Nityo nityānāṁ cetanaś cetanānām eko bahūnāṁ yo vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). These are Vedic mantras. We have to understand the transcendental science through Vedic knowledge. By our imperfect knowledge, if we try to understand the Absolute Truth, naturally we shall find Him.
We can imagine. Just like gagana-sadṛśa. So God is great, but we have no knowledge how He is great. We can simply think of gagana, the sky. That is the greatest. That is our... But we do not know that millions of skies are within the belly of the Supreme Personality of Godhead. There our estimation, gagana-sadṛśa, is imperfect. How He can be gagana-sadṛśa? Yasyaika-niśvasita-kālam athāvalambya jīvanti loma-vilajā jagad-aṇḍa-nāthāḥ (Bs. 5.48). Jagad-aṇḍa-nāthāḥ. Jagad-aṇḍa means universe, and the gagana is within the universe. Gagana, we cannot see beyond this gagana, but beyond this gagana there is another gagana. In the Bhagavad-gītā... You are reading Bhagavad-gītā. You must know it. Paras tasmāt tu bhāvaḥ anyaḥ: (BG 8.20) "There is another sky, spiritual sky." Sanātana. Paras tasmāt tu bhāvaḥ anyaḥ avyaktaḥ avyaktāt sanātanaḥ, sarveṣu naśyatsu na vinaśyati. This gagana will be annihilated at the time of destruction, but that does not annihilate.
So the idea of gagana is not perfect idea of the Supreme. Gagana-sadṛśa, that is limited within the purview of our knowledge because we cannot think that anything can be greater than this big sky. No, He is mahato mahīyān, bigger than the biggest, aṇor aṇīyān, smaller than the smallest. Just like we can imagine atom, the smallest. But atom we can see by some way or other atom. Six atoms, trasareṇu. Six atoms, when it is combined, we can see through the windows with the sunshine so many trasareṇu. Those small particles which we see through the window with sunshine, they are combination of six atoms. They are not original atom. But the atomic constitution of the living entity is a thousand times smaller than the atom. Therefore aṇor aṇīyān mahato mahīyān: "He is greater than the greatest and smaller than the smallest." The smaller than the smallest, we are. We are also part and parcel. Just like the sun and the sunshine. The sunshine is combination of small atomic molecular parts, shining parts. They are also different. They are not combined together. That is scientific. Similarly, we are also sparks of the Supreme Personality of Godhead. Mamaivāṁśo jīva-bhūtaḥ (BG 15.7). You are reading Bhagavad-gītā. You know. That aṁśa, that is described already—one ten-thousandth part of the point. Mamaivāṁśo jīva bhūtaḥ (BG 15.7). In another place, jīva-bhūtāṁ mahā-bāho yayedaṁ dhāryate jagat (BG 7.5). This material world is important because it is being manipulated by that small spiritual spark, jīva-bhūtāṁ mahā-bāho.
So we are small particles, part and parcel of the Supreme, and they are distributed all over His creation, brahmajyoti. That is nirākāra. But the brahmajyoti is not the ultimate truth. Brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11). The first realization... Just like light in the morning. When you see light, you see the light of the sun. But that is not very important thing, sunlight. Of course, we have no other means to understand beyond the sunlight, but we take it sunlight is very important. Actually very important because through sunlight the whole universe is maintained. It is sunlight. As soon as there is shortage of sunlight, the place becomes immediately condemned. As soon as there is sunlight, we feel pleasure, "Oh, today is very sunny day, nice." So sunlight is always there, but it is being covered. The sunlight is not covered, sun is not covered, but our eyes are covered. Suppose there is cloud. A cloud may expand, say, a hundred miles. But do you think the sunlight is a hundred miles? You cannot estimate, millions and millions of miles. So what hundred-miles cloud can cover the sun? The hundred-miles cloud can cover my eyes. And we say, "Today sun is covered by the cloud." That is our ignorance.
Similarly, the Supreme Brahman, who is spreading the effulgence of light, He cannot be covered. We are covered. We, the small particles, we are covered. Mohita. Tribhir guṇamayair bhāvair mohitam. Mām eva nābhijānāti. In the Bhagavad-gītā this is. They are bewildered by this external energy. Their eyes have been covered. Their eyes... Our, because we are very small, so our senses, the capacity of the senses, they are also limited. Although we have got all the qualities, because fire and a spark of fire qualitatively the same, but quantitatively different. Similarly, we are Brahman, and Kṛṣṇa is Parabrahman, Supreme Brahman. Nityo nityānām, the chief of the all eternals. Cetanaś cetanānām. He is the supreme living entity of all living entities. He is also living entity. So if I am a living entity, I have got a form, so why the supreme living entity will not have a form? This is poor fund of knowledge. He is not nirākāra. But we cannot estimate His ākāra. That is nirākāra. Nirākāra means to estimate. We cannot estimate how big He is. That means nirā... Nirākāra does not mean formless. When there is in the śāstra, nirākāra, this word is used, nirākāra means He has no prakṛta-ākāra, material form. That is nirākāra, not that he has no form. That is poor fund of knowledge. He is sac-cid-ānanda-vigraha (Bs. 5.1). Therefore Kṛṣṇa says in the Bhagavad-gītā, avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam: (BG 9.11) "My original form is like human being." And the Bible also it is said, "Man is made after the form of God."
