teṣu - toward them; rājā - the King (Dhṛtarāṣṭra); ambikā - of Ambikā; putraḥ - the son; bhrātṛ - of his brother; putreṣu - toward the sons; dīna-dhīḥ - whose mind is wretched; samaḥ - equally disposed; na vartate - is not; nūnam - surely; duḥ - wicked; putra - of his sons; vaśa-gaḥ - under the control; andha - blinded; dṛk - whose vision.

Indeed, weak-minded Dhṛtarāṣṭra, the son of Ambikā, has come under the control of his wicked sons, and therefore that blind King is not treating his brother’s sons fairly.
