In plain words
So it is by nature inert. It is filled with impurity.
A hovel of filth, a servant's basket rotting with disease, a tuber that stirs from its birth, a thornbush that cannot cross the ocean of worldly life, a quiver of arrows: rise and look! However we may prize it in thought, never trust this body as steady, O Manas; take refuge at the feet of Hari.
So they have taught about this body.
The body is made of the five elements; the body must fall, sooner or later; the indweller is free of every ill; reckon it well: for the indweller, death and birth, the marks of the bonds that tie by attachment, there are none; look at the truth: that indweller is the God of gods; ponder it in your mind: He is the Ātma Himself.
This body is what you, who are that God of gods, have put on. The body you have put on, you may choose it, you may enjoy it; but in what way are you to choose it, in what way are you to enjoy it? You must have it with that discriminating knowledge.
It has one more name: śarīra. Its derivation. They said, 'śīryate iti śarīraḥ'. That is, this śarīra is what wears away and wastes away. When it is born, it is a lump of blood. It draws people by its tenderness. Little by little it enters youth. Through its beauty and charm it displays Ahaṅkāra. After that it enters old age. It becomes ugly. This śarīra changes in many ways. Because it wears away and changes, it has the name śarīra.
This śarīra has a third name as well. Namely, that this very thing is a temple. Many people have been saying so. For what purpose was this temple formed? 'Deho devālaya prokto jīvo devassanātanaḥ.' For the jīva, who is God, this body was built as a temple. How should we use the temple? It is the holy, divine dwelling of God. This body, the dwelling of God, must never be misused at all. You must use it on the proper path, on the holy path.
