तत्त्वमसिप्रकरणम् ॥ १८ ॥ CHAPTER XVIII 'THOU ART THAT' येनात्मना विलीयन्ते उद्भवन्ति च वृत्तयः । नित्यावगतये तस्मै नमो धीप्रत्ययात्मने ॥ १ ॥

1. I bow down to that Eternal consciousness, the Self of the modifications of the intellect, in which¹ they merge² and from which they spring.³ प्रमथ्य वज्रोपमयुक्तिसंभृतैः श्रुतेररातीञ्शतशो वचोऽसिभिः । ररक्ष वेदार्थनिधिं विशालधीर्नमो यतीन्द्राय गुरोर्गरीयसे ॥ २ ॥
2. I bow down to the great mendicant, the Teacher of my Teacher who, of great intellect, routed hundreds of enemies of the Sruti by means of words comparable to swords and made impenetrable through thunder-like reasoning, and who protected the treasure of the real import of the Vedas. नित्यमुक्तः सदेवास्मीत्येवं चेन्न भवेन्मतिः । किमर्थं श्रावयत्येव मातृवच्छ्रुतिरादरात् ॥ ३ ॥ ¹ Just as circles of fire (e.g., in a revolving torch) merge in and spring from fire. ² E.g., during deep sleep. ³ E.g., during waking and dream when they spring from the Self.
