In plain words
All the ancients:
Subtle in the subtle atom, great in the great object, shining everywhere as the onlooker of all, the Ātma is the atom; the atom becomes Brahman.
Brahman, the atom and the Ātma: the three are only synonyms. It took the scientists a thousand years to learn that the Divinity everywhere is one. But what they have learnt is the size of a small mustard seed. They take pride the size of a pumpkin.
Prahlāda's rapture in God
The little boy Prahlāda recognised this truth some thousands of years ago, in the Kṛta age. This very principle:
That He is here and not there, have no such doubt; the Wielder of the discus is everywhere; wherever you search and look, there He is.....
So Prahlāda declared in those days. Wherever you look, the principle of God alone is there. Wherever you look, the principle of the atom alone is there. The principle of the atom itself is Divinity. Because he recognised the oneness called Divinity that is in the atom and in the vast, Prahlāda achieved everything, and because he changed his attachment to the body, he merged in Divinity. Had he had attachment to the body, when they threw him down from the mountain he would have been afraid, ‘Alas, I may fall!’ But he had none. He fell, laughing and saying ‘Nārāyaṇa, Nārāyaṇa’. When they brought rutting elephants to trample him, even then he had no fear of ‘what will become of me if the rutting elephant tramples me?’ He kept on laughing and saying ‘Nārāyaṇa, Nārāyaṇa’. They kept having him bitten by poisonous snakes. He looked at them, took them up like flowers and said, ‘Nārāyaṇa, Nārāyaṇa’. In this way, at all times, he let go of attachment to the body and lived with attachment to God alone. That is why he kept proclaiming to the world that every atom is God. His teachers came to Hiraṇyakaśipu: ‘Sir! What is this child's greatness? He has not the slightest attachment to the body.
When the demons stabbed him again and again, the demon's son, ‘O You who rest on the serpent! O Breaker of demons! O Lord of the world! O Refuge of those in great distress! O Purifier of all!’ so he praised; but he sheds no tears from his eyes, nor trembles with fear, O King!
So small a child has no such thing as fear. He shed no tears. With Ānanda, with great eagerness and gladness, he is contemplating God.’ That is, for every person who has recognised Divinity there is constant Ānanda, and no sorrow at all. Who grieves? Only those with attachment to the body grieve. They worry and grieve over the hardships, losses, sorrows and troubles of this body. The body is a tool. What is born must die. Along with birth, death came with it. Why should we grieve? For one who has recognised the truth that it cannot be escaped, whenever it comes, there is constant Ānanda.
The Gopīs' absorption in Him
The Gopīs kept praying to Kṛṣṇa and wondering in many ways. How are we to describe You, Kṛṣṇa! How are we to know You? What form are we to meditate on? What name are we to keep in mind? We do not know. Why?..
You are subtler in form than the atom, far vaster than the vast; in the eighty-four lakh kinds of living beings You dwell, never leaving them, they say; from the atom, the speck of dust, the blade of grass, the stick of wood, You shine in undivided form, they say. Kṛṣṇa!
