Acharya Prashant addresses the question of how to determine if the advice given by elders or others is correct. He explains that to judge the weight or truth of anyone's words, one must first be awake and alert. He uses the analogy of a sleeping person or someone who is half-awake to illustrate that such individuals cannot accurately perceive reality or understand what is being said. A person who is distracted or only partially listening is even more dangerous than one who is asleep, as they tend to misinterpret and distort the meaning of the words they hear. Therefore, the primary concern should not be the validity of the elder's advice, but rather one's own state of consciousness.
