I) Your title question Is everything which can be seen with two physical eyes Me(Brahman or Atman) alone?
Jiva is non-different from Brahman because both are Chaitanyam (????????/consciousness), in accordance with 20th sloka(verse) of Brahmajnānāvalimālā, which is ?????? ????? ?????????? ???? ???????? ????? ?
???? ?????? ?????????????? ??????????????? ? ???. which means Brahman is alone real the world is Mithya; ?iva is non-different from Brahman
.
That is, this Jagat is superimposed (Adhyāsa/??????) on Brahman as Adhishtānam (????????/substratum) by Vikshepa Sakti of Māyā. Due to ignorance (avidyā or ajnānam), Jīvātmans see the jagat (Vyāvahārikā Sattā/Relative Reality) alone rather than Brahman (Pāramarthika Sattā/Absolute Reality)
Chandogya Upanishad [3.14.1] says Sarvam khalvidam Brahman
which means Everything comes from Brahman, everything goes back to Brahman, and everything is sustained by Brahman. One should therefore quietly meditate on Brahman.
Thus, from aforementioned upanishad, your claim Everything which is here in this world Me Myself
holds good because Me (self/Jiva) is nothing but cetana (????/conscious principle), which is non-different from Brahman. This consciousness, that is Me alone
, is projected as jagat by Māyā ; as long as āvarana Sakti of Māyā veils brahman, He will not be visible. The moment ātma-Jnānam is dawned, this veil will disappear and Brahma-Sākshātkāram
(???????-?????????????) will be attained (i.e. Brahman will be seen with this two physical eyes).
