Brahman is truth, knowledge, infinite. He who knows it as set in the cave of the heart, in the highest ether, attains all desires together with the wise Brahman.
Taittiriya Upanishad
तैत्तिरीयोपनिषद्
मूल श्लोकः
सत्यं ज्ञानमनन्तं ब्रह्म। यो वेद निहितं गुहायां परमे व्योमन्। सोऽश्नुते सर्वान् कामान् सह ब्रह्मणा विपश्चितेति॥
satyaṁ jñānam anantaṁ brahma yo veda nihitaṁ guhāyāṁ parame vyoman so 'śnute sarvān kāmān saha brahmaṇā vipaścitā iti
