Mandukya Karika 1.18

Sanskrit Verse

विकल्पो विनिवर्तेत कल्पितो यदि केनचित् ।
उपदेशादयं वादो ज्ञाते द्वैतं न विद्यते ॥ १८ ॥

Transliteration

vikalpo vinivarteta kalpito yadi kenacit |
upadeśādayaṃ vādo jñāte dvaitaṃ na vidyate || 18 ||

Translation

If anyone has ever imagined the manifold ideas (such for instance as the teacher, the taught, and the scripture), they might disappear. This explanation is for the purpose of teaching. Duality (implied in explanation) ceases to exist when the Highest Truth is known.
