According to Hindu theology, there is Ishvara, the Supreme (cosmic) being, and the Trimurti personified by Brahma, Vishnu and Shiva. Nothing about Yhvh specifically. In different schools of Hinduism, Ishvara is defined (or not defined) as the Creator God.

So, according to those philosophies, the Demiurge is subordinate to the Supreme Being but is the creator of the physical world (or the creator or evil). When was Yhvh specifically considered to be the Demiurge?
I understand he is linked to El, a name that originates from Canaan and the Levant. Now, if you permit, I’m gonna quote Wiki (that lists its sources: numbers in brackets). Some might find that info useful.
Specific deities known as El or Il include the supreme god of the Canaanite religion[3] and the supreme god of the Mesopotamian Semites in the pre-Sargonic period.[4]
The Hebrew form (אל) appears in Latin letters in Standard Hebrew transcription as El and in Tiberian Hebrew transcription as ʾĒl. El is a generic word for god that could be used for any god, including Hadad, Moloch,[26] or Yahweh.

Yahweh was the national god of the Iron Age kingdoms of Israel (Samaria) and Judah.[3] His exact origins are disputed, although they reach back to the early Iron Age and even the Late Bronze:[4][5] his name may have begun as an epithet of El, head of the Bronze Age Canaanite pantheon,[6] but the earliest plausible mentions are in Egyptian texts that place him among the nomads of the southern Transjordan.[7]
By the end of the Babylonian exile (6th century BCE), the very existence of foreign gods was denied, and Yahweh was proclaimed as the creator of the cosmos and the true god of all the world.[11] (note: “Supreme Being” or “Demiurge”?)
There is almost no agreement on the origins and meaning of Yahweh’s name.[12] It is not attested other than among the Israelites, and seems not to have any reasonable etymology.[13]

I’m curious as to where does Yhvh stand in Hindu mythology…
