Sūrya–Nāga Dialogue on the Perfected Gleaner-Ascetic
अनादिनिधनं लोके चक्रहस्तं च मां मुने । अनुध्यानान्मम मुने नैतद् वचनमन्यथा
anādinidhanaṁ loke cakrahastaṁ ca māṁ mune | anudhyānān mama mune naitad vacanam anyathā ||
毗舍波耶那说道：“噢，仙人啊，只要恒常观想于我，你将在此世见我为无始无终之主，手执神轮（查克拉）。此言于你，仙人啊，永不有异（绝不虚妄）。”

Educational Q&A
Sustained meditation (anudhyāna) on the Lord leads to direct experiential vision of the divine form; the verse also emphasizes the reliability of divine assurance—true contemplation yields a true result.
Vaiśaṃpāyana reports a promise addressed to a sage: if the sage continually contemplates the Lord, he will see the beginningless, endless deity in the recognizable Viṣṇu form holding the discus, and this promise will not fail.
