In response to a question about the authenticity of various versions of the Bhagavad Gita, Acharya Prashant advises to first and foremost avoid the commentary part. He states that it is in the commentaries where the maximum adulteration and mischief occur, as various commentators push their own agendas. He recommends limiting oneself to just the translation of the verses, preferably from a source that translates each word individually and correctly into one's preferred language. There is no need to read detailed commentaries, as this is where the most mischief takes place. Secondly, the speaker emphasizes that the Gita must agree with the Upanishads and cannot contain anything that goes against the basic tenets of Vedanta. If any interpretation of a Gita verse is not in sync with Vedantic philosophy, that interpretation must be immediately rejected. The Gita is an integral part of Vedanta, and for understanding Vedanta, Acharya Shankara is the leading authority, so it makes sense to begin with his commentary (Bhashya). Any interpretation that contradicts the core Vedantic verses or the Mahavakyas is false. Acharya Prashant explains that due to its popularity, the Gita has been exploited by many with distorted ideologies to validate their own philosophies and gain credibility. They interpret the scripture to show that the Gita says the same thing as their own guru, even if the guru was ignorant and not speaking of Vedanta. This is a disrespectful and deliberate distortion of the verses' meanings. For instance, where a verse contains the word 'Buddhi' (intellect), a translator might write 'Bhakti' (devotion), which is described as culpable disobedience. Instead of following what Shri Krishna says, they try to make Krishna follow their ideology. He concludes by warning that the Gita has suffered from its popularity, as many use it to sanction their own beliefs by misinterpreting verses. He advises being very careful, especially with interpretations that have arisen in the recent past, and suggests that texts from Gita Press, Ramakrishna Mission, and Chinmaya Mission are generally reliable. He reiterates that if doubts persist, one should refer to the Upanishads and their core philosophy to correctly interpret the Gita.
