Acharya Prashant explains that the difficulty in understanding spiritual truths often arises from the effort to think and analyze rather than simply listening. He addresses the questioner's concern about the validity of their decisions and the desire for a guarantee of correctness. He clarifies that the Shrimad Bhagavad Gita is not inherently right or wrong; rather, it is the observer's vision that determines what they perceive. A person with a violent mindset will find justification for violence in the scripture, while a pure vision will see something else. Therefore, the focus should be on purifying one's own vision rather than seeking external validation.
