Here is the Sanskrit anuvad, Hindi anuvad, and English translation of Ksetra-Ksetrajna-Vibhaga Yoga Chapter 13, Verse 13.13.
Sanskrit
ज्ञेयं यत्तत्प्रवक्ष्यामि यज्ज्ञात्वामृतमश्नुते । अनादि मत्परं ब्रह्म न सत्तन्नासदुच्यते ॥ १३.१३ ॥
Hindi
जो जाननेयोग्य है तथा जिसको जानकर मनुष्य परमानन्दको प्राप्त होता है, उसको भलीभाँति कहूँगा। वह अनादिवाला परमब्रह्म न सत् ही कहा जाता है, न असत् ही|
English
I shall now state that which has to be known, knowing which one attains to immortality; the Supreme Brahman is beginningless and he is called neither ‘Sat’ (being) nor ‘Asat’ (non-being).
