Quote by Chandogya Upanishad: “All this is Brahman.”

This declaration signifies that the entire universe, with all its diversity, is a manifestation of the single ultimate reality, Brahman. It encourages a perception of unity in all things, fostering a sense of interconnectedness and divine presence in every aspect of existence.

This foundational statement encapsulates the monistic view of reality prevalent in the Upanishads, shaping the spiritual landscape of ancient India by defining the nature of the cosmos and the divine.

One of the principal Upanishads of ancient Indian philosophy, believed to have been composed between 800 and 600 BCE during the Vedic period. It contains some of the most important early formulations of Vedantic philosophy, including the mahavakya (great sayings) that became central to Advaita thought. The text is embedded in the Sama Veda tradition.
