SB Canto 3

The atom is described as an invisible particle, but when six such atoms combine together, they are called a trasareṇu, and this is visible in the sunshine pouring through the holes of a window screen.

SB 3.11.5, Translation and Purport:

The division of gross time is calculated as follows: two atoms make one double atom, and three double atoms make one hexatom. This hexatom is visible in the sunshine which enters through the holes of a window screen. One can clearly see that the hexatom goes up towards the sky.

The atom is described as an invisible particle, but when six such atoms combine together, they are called a trasareṇu, and this is visible in the sunshine pouring through the holes of a window screen.

CC Adi-lila

CC Adi 5.70, Translation:

Just as atomic particles of dust pass through the openings of a window, so the networks of universes pass through the pores of the skin of the puruṣa.

Krsna, The Supreme Personality of Godhead

Just as innumerable atomic infinitesimal fragments pass through the holes of a screened window, so millions and trillions of universes in their seedling form are coming out from the bodily pores of Mahā-Viṣṇu.

Krsna Book 14:

Lord Brahmā realized his actual position. He is certainly the supreme teacher of this universe, in charge of the production of material nature, consisting of the complete material energy, false ego, sky, air, fire, water and earth. Such a universe may be gigantic, but it can be measured, just as we measure our body as seven spans. Generally everyone's personal bodily measurement is calculated to be seven spans of his hand. This particular universe may appear as a very gigantic body, but it is nothing but the measurement of seven spans for Lord Brahmā. Aside from this universe, there are unlimited other universes which are outside the jurisdiction of this particular Lord Brahmā. Just as innumerable atomic infinitesimal fragments pass through the holes of a screened window, so millions and trillions of universes in their seedling form are coming out from the bodily pores of Mahā-Viṣṇu, and that Mahā-Viṣṇu is but a part of a part of the plenary expansion of Kṛṣṇa. Under these circumstances, although Lord Brahmā is the supreme creature within this universe, what is his importance in the presence of Lord Kṛṣṇa?

Bhagavad-gita As It Is Lectures

Even the material atom also we cannot see. When the material atoms are combined into six, then you can see floating in the air through the sunshine which is entering your room through the holes of a window. You can see some particles.

Lecture on BG 4.11 -- New York, July 27, 1966:

In the modern age, the atomic age, the scientists have discovered the force, the power of material atoms. But they have not yet known what is the force of spiritual atom. There is spiritual atom. We are spiritual atom. The atom is described in the Vedic literature, the form of the spirit which we are actually. Keśāgra-śata-bhāgasya śatadhā kalpitasya ca (CC Madhya 19.140).

Keśāgra... Keśa means the hair, the upper portion of your hair. When it is divided into ten thousand parts... And just imagine. That one part is the spiritual atom. It is so small, it is so minute, that it is not possible to see with our material eyes. Even the material atom also we cannot see. When the material atoms are combined into six, then you can see floating in the air through the sunshine which is entering your room through the holes of a window. You can see some particles. That small particle, they are combination of six atoms. That particle, when it is divided into six, that becomes the atom. So you cannot see even the material atom, and what to speak of the spiritual 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.

Lecture on BG 7.1 -- Auckland, April 15, 1972:

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.

Initiation Lectures

We can see the atoms within the holes of the windows when there is focus of sunlight. That is called prasareṇu. Prasareṇu means six atoms combined together, then it is visible. Otherwise, atom is also not visible with our naked eyes.

Initiation Lecture -- Hamburg, August 27, 1969:

God and ourself, Kṛṣṇa and living entities, they are qualitatively one, but quantitatively, we are very minute. Aṇu. We are smaller than the atom. Nowadays there is atomic theory. We can see the atoms within the holes of the windows when there is focus of sunlight. That is called prasareṇu. Prasareṇu means six atoms combined together, then it is visible. Otherwise, atom is also not visible with our naked eyes. There is atomic theory, paramāṇuvāda, in Vedic literature also. And Bhāgavata says that the scientists may be one day able to count how many atoms are there within this universe. This is not possible, of course, but it is theoretically. The Vedic, er, Śrīmad-Bhāgavata says that "It may be possible one day by scientific research, one can count how many atoms are there within this cosmic manifestation. Still, it is not possible to know the Supreme Personality of Godhead by our ordinary sense perception.
