About Brahman
In the Vedanta traditions of Indian philosophy, the word Brahman refers to what is claimed to be the fundamental reality that exists regardless of how humans perceive or divide the world. It is described as the underlying basis of everything that exists. According to these traditions, all particular things, objects, people, events are not ultimately separate entities. They are expressions or appearances of that underlying reality. In other words, multiplicity is treated as a secondary level, while Brahman is supposed to be the primary level.
Notice the structure of the claim. Vedanta philosophers argue that ordinary perception divides the world into many separate objects because of how the mind operates. This division is called Maya. Maya does not necessarily mean that the world is nonexistent, like a hallucination. Instead, it means that the way we interpret what we perceive is considered mistaken or incomplete. The error is the belief that separate things exist independently and permanently. From the Vedanta viewpoint, that belief is wrong because everything is ultimately one reality called Brahman appearing in many forms.
In that framework, suffering is explained as a consequence of identifying with a limited individual self that believes it is separate from the rest of reality. If someone believes they are a distinct entity struggling inside a world of other distinct entities, they experience fear, attachment, and loss. Liberation, often called moksha, is defined as the realization that the individual self and Brahman are not actually separate. The supposed goal is to remove the mistaken identification with the individual perspective.
But here is the critical point that is often skipped in popular explanations, the claim that Brahman is the deeper truth is not something that can be verified the way scientific claims can be verified. It is a metaphysical assertion supported by philosophical reasoning and tradition, not by independent observation that could confirm it from outside the system. In that sense, it is very different from what Immanuel Kant was doing. Kant argued that we cannot access reality outside the conditions of our cognition at all. Vedanta claims the opposite, that it is possible to realize the underlying reality directly. Those two positions are structurally incompatible.
Also, when Vedanta says the world is “illusion,” people often misunderstand it. The claim is not that physical events do not occur. The claim is that the interpretation of those events as separate, independent entities is mistaken relative to the supposed unity of Brahman. So the “illusion” is about how things are categorized and understood, not necessarily about whether experiences occur.
However, there is an unresolved problem in this philosophy that critics often point out. If Brahman is the only true reality, and Maya is a distortion, then one must explain how that distortion arises within a reality that is supposed to be complete and unified. Different Vedanta schools give different answers, but none of them remove the logical tension entirely. This is why many philosophers treat Maya not as a proven insight about reality but as a metaphysical framework that organizes certain experiences and interpretations.
So if you strip away the mystical language, Vedanta claims there is one underlying reality, that humans misinterpret it as many separate things, and that correcting this interpretation removes psychological conflict. Whether that is an actual discovery about reality or a conceptual system built to reinterpret experience is still debated. Declaring the world an illusion often says more about the theory someone adopts than about the structure of the world itself.
