Many of us don’t know about the difference between The Supreme Lord (Param Brahma) and Devata. Devatas are Indra, Varun, Agni, Suriya, Chandra etc. Devatas have their own shape and they can also change their shape anytime if they want. Devatas have a lot of power.
But the mistake that usually done by us is that we call Devata as God or Godess. If we address them as God then Hinduism will be polytheistic(Belive in many Gods and Goddess). But the reality is Hindusim is a monotheistic. In 1.164.46 of the Rig Veda states-
"They call him Indra, Mitra, Varuṇa, Agni, and he is heavenly nobly-winged Garutmān.To what is One, sages give many a title they call it Agni, Yama, Mātariśvan."In Holy Vedas, The Supreme Lord is mentioned as “Param Brahma”. The word Brahma means the Creator. But there’s a difference between “Brahma Dev” and “Param Brahma.” “Brahma Dev” is a Trimurti with Lord Shiva and Lord Vishnu. Devatas are the symbol of power of Param Brahma. In serval Purans it is mentioned that many Devatas were born for many causes. But the Supreme Lord never Born. He has no shape, he is Adi..Ananta.
The word ‘ॐ’ is the symbol of Supreme Lord. Actually Trimutri is called as ॐ. The world Om is consist of three alphabet. They are-
A….U….M “A” means- Lord VishnuSo worshiping any Devata-Devi is worshiping one God, the Supreme Lord. Omakar mediation is also a way of worshiping Supreme Lord.
“U” means- Lord Shiva
“M” means- Lord Brahma(Brahma Dev)
