Acharya Prashant explains that Vedanta is the culmination of the philosophy of the Vedas, representing their topmost philosophical content. Originating in India, it serves as the root from which all Indian philosophical systems, religions, and sects derive their nutrition and inspiration. He asserts that there can be no spirituality without Vedanta, as it addresses fundamental issues necessary for anyone who wishes to live in truth and understand life. He clarifies that Vedanta is not a belief system, as it carries no dogmas, fables, or stories. Unlike religions, it is exploratory and does not require one to take anything for granted. While some might call it experiential, Acharya Prashant notes that even experience is subjective and flawed because it depends on the experiencer. Vedanta operates with a level of rigor that questions the very entity that says "I," investigating its origin and trustworthiness. Regarding its components and age, he states that Vedanta consists of the Upanishads, the Bhagavad Gita, and the Brahma Sutra, with the Upanishads being the cornerstone. The oldest Upanishads were composed approximately 4,000 years ago, and the tradition has continued through various eras, including the Buddhist and Christian eras. These texts are often excerpts from the Vedas, and their genesis is spread over a vast stretch of time.
