Parabrahma
Adi Shankara has said that there is only one Supreme Para-Brahman and all the other deities are the forms and expansions of this Para-Brahman. It is believed that all Vaishnava and other schools attribute Personhood to this concept, as in Svayam bhagavan. Under terms of some schools of Vedanta, It has three modal aspects with a highest as Para Brahman or Lord Vishnu.ParaBrahman means Supreme Brahman, or Supreme Cosmic Spirit, or Godhead. Although an ineffable entity, it could be said to be that which contains and pervades the universe. ParaBrahman, from beyond, encompasses the transcendent and immanent ultimate reality, Brahman. The Absolute Truth is both subject and object, so there is no qualitative difference. Terms like Parameshvara, Ishvara, Bhagavan, Brahman, Paramatma are held to be synonymous with ParaBrahman. Shaktas consider Adi parashakti considered as power of ParaBrahman. Hindu sects like Shaivism, Vaishnavism and Shaktism have concept of ParaBrahman. However, in contrast with Vaishnavism where ParaBrahman denotes Saguna Brahman as Hari or Vishnu, either Saguna Brahman or the impersonal Nirguna Brahman may be connotated by other sects.
