Mundaka 5.06
सत्यमेव जयति नानृतं सत्येन पङ्था विततो देवयानः। येनाक्रमन्ति ऋषयो ह्याप्तकामा यत्र तत्सत्यस्य परमं निधानम् ॥६॥
Truth alone triumphs, not falsehood. By truth is laid out the path of the divine, on which sages, having fulfilled their desires, advance to the supreme abode of truth.
Bhāshya 5.06
Lord Vishnu is proclaimed as truth, the real, due to his good qualities. Vaikuntha is the abode of Lord Vishnu, the supreme world.
"सत्यो हि भगवान् विष्णुः सद्गुणत्वात् प्रकीर्तितः। आसुरास्तद्विरुद्धत्वादनृताः परिकीर्तिताः। तस्य विष्णोर्निधानं तु वैकुण्ठो लोक उत्तमः॥"
"Indeed, the Lord Vishnu is proclaimed as truth, the real, due to his good qualities. Demons, due to opposition to that, are proclaimed as untruthful. Vaikuntha is the abode of Lord Vishnu, the supreme world."
इति च॥
- stated thus, as well.
