Acharya Prashant discusses the historical decline of India, attributing it to two main factors: the neglect of Vedanta, which led to internal weakness, and the over-reliance on ritualism, which hindered material and scientific progress. He notes that while the Bhagavad Gita and the Vedas are widely known, people often ignore Shri Krishna's clear warnings against ritualism driven by desires. He explains that knowledge does not stay in a mind filled with worldly cravings, as ritualism is primarily used to fulfill lower desires rather than seeking liberation.
