I have come across some observations which depict an interesting correlation between God and light in the major world religions.... In Hinduism, the Vedas and Hindu scriptures considers the Shivalinga as representing a cosmic pillar of light. The Dharmic monotheistic sect the Prajapita Brahmakumaris consider God to be a point of light. The Upanishads and enlightened masters have also described Brahman to be self-luminous. In Islam, Allah has 100 name's, and one of them is Alnoor ( the Light). “God is light,” says Jesus Christ (1 John 1:5), in the Bible in Christianity. In Judaism, Psalm 76:4 says of God, “You are radiant with light.” So this correlation between God and light, is a common denominator in these four major world religions. Imo, the fire worship in Zoroastrianism may be illustrating this correlation between God (Ahura Mazda ) and light as well, light being emitted by the fire. I would say this may provide more proof that the major world religions are identical in their core, with only superficial differences on the outside creating cause for extremism and conflict. If you find any further proofs or evidences in this regard, please do share it here. Thanking in advance.
