Those small particles which we see through the window with sunshine, they are combination of six atom. 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. 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, brahma-jyotir. That is nirākāra. But this brahma-jyotir 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.
