Ishavasya Upanishad: Mantra 6

यस्तु सर्वाणि भूतान्यात्मन्येवानुपश्यति । सर्वभूतेषु चात्मानं ततो न विजुगुप्सते॥ ६॥ yas tu sarvāa¹‡i bhÅ«tāny ātmany evānupaśyati sarva-bhÅ«tea¹£u cātmānaa¹ tato na vijugupsate Translation: He who sees everything and everyone in the Self alone, and sees the Self in everything and everyone, hates not anything or anyone. Commentary: He who sees everything and everyone in the Self alone, and sees the Self in everything and everyone, hates not anything or anyone. In the Bhagavad-gÄ«tā (15.7) it says: mamaivāa¹Å›o jÄ«va-loke jÄ«va-bhÅ«taa¸¥ sanātanaa¸¥ manaa¸¥-a¹£aa¹£a¹­hānÄ«ndriyāa¹‡i praka¹›ti-sthāni kara¹£ati "An eternal portion of Myself, having become an individual embodied soul in this world, associates with the senses, including the mind, and activates them". It is affirmed here that what you really are is an eternal portion of "Myself". That is, God lies in you... as you... your true and authentic nature is Divine... The fact that the Self that lies in the depth of every living being and the Supreme and Absolute Self, named Brahman by the Adwaita Vedānta, are one and the same, is clearly supported by the revealed scriptures. As an example we can see the Ba¹›hadāraa¹‡yaka Upania¹£ad (2.5.19): ayam ātmān Brahman... which means "this Ātman is Brahman" and in the same text (1.4.10) we find that most famous phrase: ahaa¹ BramāsmÄ«ti ... or ... ahaa¹ Brahmāsmi... or "I am Brahman". We also find the great mahāvākya: tat tvam asi or "thou art That", in the Chāndogya Upania¹£ad (6.8.7), in the dialogue between Uddālaka and his son Śvetaketu... Finally I shall quote that magisterial phrase of the great Ādi Śaa¹…karācārya... brahma satyaa¹ jagan mithyā... or "Brahman is the reality, the world is false".
