There are some words for the almighty in Hindu
philosophy and people think that all words denote to one supreme power. These five popular words are Brahm, Parmatma, Atma, Ishwar and Bhagwan used for
almighty. The first three words Brahm, Parmatma, Atma are one and denotes to
unexplainable, bodiless, shapeless almighty power but Ishwar and bhagwan used
for that almighty power when Brahm come in to the matter(substance) with his full
divinity. Divinity means what is the best or absolute that is in Bhagwan ie God.
Bhagwadgita advocated the divinity of God in its chapter ten and eleven. Here
he is called Sagun-brahm. No one can worship Brahm, Parmatma or Atma because
that is only achievable. People all over
the world worship Ishwar or Bhagwan in different forms, what the name
may be. The God with full divinity is worshiped as bodiless or with in body.
The cosmos is the expension of brahm, each and
every thing from dust to consciousness is the expension of brahm.
Some scholars believe consciousness is parmatma
but it is untrue vision. If consciousness is parmatma than what is matter(substance),
because everything is brahm and this universe is the expension of brahma. Actualy
parmatma is an ultimate reality with absolute knowledge, wisdom and intelligence and
repetedly described from vedant to Bhagwadgita as pure and undisturbed stage of Gyan and the force
generate from him is the cause of consciousness and matter.
