In plain words
Man today does not develop pure, holy, divine feelings at all. Man enters into this thing called desire and forgets his humanness.
Humanness came from Mādhava; why has Mādhava-ness been hidden? Māyā, Māyā: this is how he became a man on earth; is not the human being a man of Māyā?
Māyā, Māyā, humanness. What is this ‘Māyā’? Delusion is Māyā; Brahman is God. So long as Māyā remains, so long as delusion remains, we cannot understand Brahman. Desires are not wrong. Desires must be there! But desires that go beyond bounds bring confusion to man's mind. Within humanness, youth is more dangerous still. Through this very youth, humanness turns into something different. In his youth a man looks on the person before him as a blade of grass. So long as there is muscle in the body, the fat in the eyes keeps growing. They keep seeing Satya as untruth and untruth as Satya. This Ahaṅkāra does not come from education. Humility alone is the ornament of education, and the most important thing of all. But Ahaṅkāra is something one buys and brings upon oneself. By it, humanness turns into nothing but demonic nature.
Humanness is the very form of these three: Ātma, Manas and body
We must recognise well the inner meaning of the word ‘naraḥ’. ‘Raḥ’ means destruction; ‘na’ means not. The one who is not destroyed is nara. Who is this nara who is not destroyed? The son of immortality. ‘Śṛṇvantu viśve amṛtasyaputraḥ’, the Upaniṣads declared. ‘O son of immortality’: so the Upaniṣad addressed him. When the letter ‘ka’ is added to such nara-hood, it turns into naraka-hood. What leads to heaven is nara-hood; what leads to hell is naraka-hood!
