What are three main aspects of the brahman?

Brahman, in Hindu philosophy, is understood as the ultimate reality or cosmic spirit that is unchanging and infinite. Three main aspects of Brahman are: Nirguna, which refers to Brahman as formless and without attributes; Saguna, which represents Brahman with specific qualities and manifestations, often seen in deities; and Aum (or Om), the sacred sound that symbolizes the essence of Brahman and the universe. Together, these aspects highlight the complexity of Brahman as both transcendent and immanent.
