Acharya Prashant addresses the common question of 'what should I do' by shifting the focus to 'who am I being' while performing an action. He explains that human beings often act out of various identities, and it is crucial to examine whether one's current state aligns with a noble character like Shri Ram or a fallen one like Ravana. He suggests that before acting, one should ask if their chosen deity or ideal would behave in the same way in that specific situation. This serves as a practical guide for those in the early stages of spiritual practice to avoid hypocrisy and align their conduct with their professed values.
