In plain words
It is not its nature to move. Because the earth turns, it seems to us as though the sun rose in the east and set in the west. This is the search for Satya! That is, ‘The sun is not the one who moves. It stays just where it is. It is we who move. Because we move, we bring about sunrise and sunset for ourselves’: in this way we must know the divinity within humanness. That very thing is what the Upaniṣads said: ‘Know yourself.’ What answer can you give to this? When someone asks, ‘Who are you?’, do you become one who knows himself merely by saying, ‘I am of such-and-such a country, of such-and-such a caste, the son of so-and-so’? This is not right. To know yourself means that we must try to recognise the principle that lies beyond all of them: the body, the Manas, the Buddhi, the citta and the Ahaṅkāra. This is what Vedānta says: ‘Neti, neti’, not this, not this. The body, the Manas, the Buddhi, the citta, the antaḥkaraṇa: these are all only instruments, nothing more! You are that very divinity which lies beyond this and makes everything shine. But when you begin such research, many hardships, pains and sorrows arise. When the devas and the asuras churned the Ocean of Milk, poison came up first of all. Only after that did Lakṣmī, Kāmadhenu, Airāvata and other precious things come up out of it. Amṛta too came only after the hālāhala.
The Heart of Man Is like the Ocean of Milk
As you churn and churn the ocean of milk called the heart with the principle called Jñāna, precious things such as kindness, compassion, forbearance, sympathy and Prema come out. The heart of man is like the Ocean of Milk. But this heart, which is such an ocean of milk, has been turning into an ocean of salt. Cruel beasts like whales, called kāma, krodha, lobha, moha, mada and mātsarya, have got into this heart. Because the traits of cruel beasts have entered the heart in which precious and sacred qualities ought to dwell, it is no longer an ocean of milk; it has turned into an ocean of salt.
