he perishes.

He who is unattached in all things, who neither exults in nor feels aversion for any good or evil that befalls him, is said to be steady in his wisdom.

A man who contemplates the objects of sense develops an attachment to them; attachment gives rise to desire, and desire results in anger.

Anger gives rise to confusion, confusion to loss of memory. Loss of memory destroys intelligence and, once a man’s intelligence is destroyed, he perishes.

But the man whose mind is disciplined and whose senses are under control is free from attachment and aversion though he moves among the objects of sense, and such a  person attains serenity.

And in that serenity, all his misery is destroyed; because the intelligence of the man of serenity is also steadied immediately.
