In plain words
He is the lord of ascetics, and his understanding is keen as a point of kuśa grass. Steadfast, he has worn down Kāma, the mind-born. He always carries a wave of joy, and the host of his inner enemies is slain.
Word for word
Lord of ascetics, whose understanding shines keen as the tip of kuśa grass, steadfast, by whom the mind-born is worn down; always carrying a wave of joy, whose host of inner enemies is slain.
