In Hindu mythology, Brahma, Vishnu and Shiva are the main Gods for creating, preserving and destroying, but who is behind all three? Where do they come from?
The Lotus Feet of Ma Kali, the goal of all spiritualists
Who is sovereign overlord of Brahma, Vishnu and Rudra? Shiva Purana and Devi Mahatmyah answer that:
"I bow to Thee, the great mother of the universe, the great Goddess, by whom formerly Brahma had been directed to create the worlds which he carried out. I bow to Thee, great support of the universe, the great Goddess, by whom formerly Vishnu had been directed to sustain the universe which he has been doing always. I bow to Thee the great mother of the universe, the great Goddess, by whom formerly Rudra had been directed to annihilate the universe which he has been doing always." (Shiva Purana, 2:2:14:30-32)
"You, who creates as Brahma, sustains as Vishnu and annihilates as Rudra, have subjected Lord Vishnu to a deep slumber. Thus, who is here capable of eulogising you? Who is capable of praising you, who pervades Vishnu, I and Rudra?" (Devi Mahatmyah 83-85)
Hence, it is Adya Kali, the beloved consort queen of Mahakala Shiva, who is the sovereign authority and primordial mother of Brahma, Vishnu and Rudra.
