Brahman is a Hindu concept describing the energy force behind the universe, the unchanging truth of why the universe is, and the source behind it. This is very different from the god Brahma, who is known as the creation aspect of the divine pantheon and is a part of the Trimurti with Shiva and Vishnu. He is not regarded in quite the same way as the great cosmic spirit, which is everlasting and greater even than the Hindu deities as the source behind creation and sustenance of the cosmos.
Jiva-muktis or liberated beings are human beings that have realized Brahman and thus their become aware of their true self; described as consciousness bliss and the highest achievable reality. However, this type of self-actualization does not accord with the Buddhist ideals of enlightenment, nirvana, which denote an awareness of the nothingness inside and with this awareness great peace and release from suffering.
Brahman in modern-day Hinduism denotes absolute reality, unchanging, the source and return of all things. Within the Hindu religion, this is an argued point and even Buddhism denotes Brahman’s as divine forms having attained Nirvana. Certain Buddhist and Hindu schools seem to collide here, though it happens later in the Buddhist tradition when scholars begin to identify Nirvana with Brahman. But the Buddha seems to have rejected the idea, saying that the desire from Brahman leads to suffering. He could find no evidence of the personal, or cosmic soul. Jains completely reject the idea of a creator god, because the universe has always been.
Brahman denotes the cosmic god that many people of the modern west refer to as “the universe”. It is the idea of cosmic divine energy that is representing when saying Namaste and recognizing the divine in another. In this way, Brahman is inherently Hindu because of their belief in the divine unison of all things.
Atman is a Sanskrit word that means inner-self or inner soul. To obtain liberation, a human must acquire self-knowledge to realize that one’s true self is identical with that of the transcendent Brahman. This refers to the Hindu idea of breaking down the body to get to the divine soul within. This is the Hindu path to enlightenment, through one of the schools of yoga. It is through realization of the Brahman within that on attains enlightenment, according to the Hindu traditions.
