The Prashna Upanishad with Shankara’s Commentary
या ते तनूर्वाचि प्रतिष्ठिता या श्रोत्रे या च चक्शुषि ।
या च मनसि सन्तता शिवां तां कुरू मोत्क्रमीः ॥ १२ ॥
yā te tanūrvāci pratiṣṭhitā yā śrotre yā ca cakśuṣi |
yā ca manasi santatā śivāṃ tāṃ kurū motkramīḥ || 12 ||
12. What form of yours is lodged in speech, what in the ear, what in the eye, and what in the mind continuous, make that propitious air do not ascend from the body.
Com.—In short, what form of yours, lodged in speech moves the mouth of the speaker, what in the ear, what in the eye, and what united with the mind acts as volition, etc., make that passive, i.e., quiet. Do not make that unquiet, by ascending from the body.
