सत्यात्मा सत्यस्वरूपो भव हे राजेन्द्र, सत्ये लोकाः प्रतिष्ठिताः तांस्तु सत्यमुखान् सत्यप्रधानान् सत्याधीनात्मलाभान् आहुः ।सत्ये हि अमृतमाहितम्; अमृतं मोक्षः ॥
In plain words
Truth-selved — be made of truth, king. The worlds are set on truth, and that is why they are called truth-faced, truth-led, worlds that get their very existence only because truth does. For the deathless is laid up in truth — and the deathless is mokṣa, freedom itself.
Close to the Sanskrit
'Truth-selved' — be of the nature of truth, O lord of kings; in truth the worlds are established, and them indeed they call truth-faced, truth-foremost, having the gaining of their own being dependent on truth. For in truth the deathless is deposited; the deathless is liberation.
