Acharya Prashant explains that attachment is a product of the mind's relationship with time. The mind, being incomplete and seeking security, perceives anything that persists over a long duration as real and true. This identification with objects, ideas, or people based solely on the length of time spent with them is what constitutes attachment. He illustrates this by noting how one can become attached even to a damp spot on a wall or a harmful relationship simply through habituation and the passage of time. He asserts that if time is removed from the equation, attachment vanishes, revealing its inherent absurdity. Furthermore, he points out that the deepest attachment is to one's own self, as it is the entity one has known for the longest duration. Regarding whether attachment is good or bad, he states that it must be judged by its consequences: if it causes grief, it is bad, and if it results in joy, it is good. He concludes that attachment usually keeps a person in grief, a fact that individuals often already know through their own experience.
