Para Brahman or Param Brahman (परब्रह्म) in Hindu philosophy is the "Supreme Brahman" that which is beyond all descriptions and conceptualisations. It is described as the formlessness (in the sense that it is devoid of Maya) that eternally pervades everything, everywhere in the universe and whatever is beyond.
Para Brahman is conceptualised in diverse ways. In the Advaita Vedanta tradition, the Para Brahman is a synonym of nirguna brahman, i.e., the attribute-less Absolute. Conversely, in Dvaita Vedanta and Vishistadvaita Vedanta traditions, the Para Brahman is defined as saguna brahman, i.e., the Absolute with attributes. In Vaishnavism, Shaivism, and Shaktism, Vishnu, Shiva, and Adi Shakti respectively are Para Brahman. Mahaganapati is considered as Para Brahman by the Ganapatya sect. Kartikeya is considered as Para Brahman by the Kaumaram sect.
Para is a Sanskrit word that means "higher" in some contexts, and "highest or supreme" in others.
Brahman in Hinduism connotes the Absolute, the Ultimate Reality in the universe. In major schools of Hindu philosophy it is the immaterial, efficient, formal and final cause of all that exists. Brahman is a key concept found in the Vedas and is extensively discussed in the early Upanishads and in Advaita Vedanta literature.
In Advaita Vedanta, the Para Brahman is defined as nirguna brahman, or Brahman without form or qualities. It is a state of complete knowledge of self as being identical with the transcendental Brahman, a state of mental-spiritual enlightenment (Jnana yoga). It contrasts with Saguna Brahman which is a state of loving awareness (Bhakti yoga). Advaita Vedanta non-dualistically holds that Brahman is divine, the Divine is Brahman, and this is identical to that which is Atman (one's soul, innermost self) and nirguna (attribute-less), infinite, love, truth, knowledge, "being-consciousness-bliss".
According to Eliot Deutsch, Nirguna Brahman is a "state of being" in which all dualistic distinctions between one's own soul and Brahman are obliterated and are overcome.
