नत्वाच्च ।न च सर्वस्यैकात्मत्वे रागादयः संभवन्ति ।'तस्माच्छान्त उपासीत' इति श्रुतेः;
In plain words
And because he is the one all bow to. And where everything has a single Self, attachment and the rest cannot arise at all. The śruti says so: "therefore worship him with a mind at rest."
Close to the Sanskrit
And because of his being bowed to. And, all having a single Self, attachment and the rest do not arise; because of the śruti, 'therefore let one worship as a calm one.'
