Acharya Prashant explains the Vedantic distinction between understanding (Vidya) and knowledge (Avidya). He describes Vidya as meditative understanding, which is reasonless, needless, and arises from a peaceful heart, whereas Avidya is material knowledge gathered from external sources for utilitarian purposes. Using the Ishopanishad, he highlights that while worshipping knowledge leads to darkness, worshipping only meditative understanding leads to even deeper darkness. The goal is to integrate both: using knowledge to navigate the world while remaining rooted in the silent understanding of the heart.
