In Rigveda, thoughts of Paramtatva are obtained in two forms :
- Pantheism : This idea of the ultimate element (paramtatva) is mentioned in the ‘Naasdiya Sukta’ of the Rigveda. It is clearly mentioned in this Sukta that only one supreme element (Param tatva) was present in the creation of universe, that in the creation of universe (world) the same element is fully expanded in all creation.
- Monism : It is mentioned in ‘Purush Sukta’. It is said in this Sukta that the basic element of creation is Virgin. It is spread all over the world.
