Acharya Prashant explains that attachment or delusion (moha) is essentially a falsehood. It is the act of believing in the existence of something that is not truly there, much like being afraid of a shadow. He advises that one should not fight their emotions but should instead investigate their root causes. Every attachment is driven by a hidden self-interest or a perceived need. He suggests that if an attachment truly fulfills a person's needs and brings lasting peace, they may keep it; however, he points out that attachment usually results in restlessness and anxiety rather than fulfillment.
