Acharya Prashant explains that the reason problems increase with age is that one becomes smarter and absorbs all the cleverness of the world. He states that for a child, the world is very simple because they have not yet absorbed much from it. As one ages and gains experience, they learn the world's cleverness, which leads to more trouble, dilemmas, and inner division. This cleverness manifests as constantly thinking about and planning for the future, treating it like an enemy to be outsmarted before it arrives. The speaker clarifies that life itself does not become complicated; rather, we become entangled. In the name of being smart, we learn the world's deceit. He contrasts the adult mind with the innocence of a child. A child is straightforward, possesses a sense of wonder, and does not carry the pain of the past into the present. When a child gets hurt, they experience the pain fully in the moment and then move on. An adult, however, is burdened by the past, and their future is merely a shadow of it. A child has little desire for attainment, whereas an adult is caught in a thousand useless entanglements, believing they are being smart and planning. This constant activity of the mind is the source of their sorrow. The speaker observes that in all of existence, only the adult human appears truly sad. Animals, plants, and even children are not burdened in the same way. The adult human is the only creature whose mind is constantly active, which is the root of their entanglement and suffering. He advises letting the mind be quiet and giving up this cleverness. While society values cleverness, seeing it as a path to success, the speaker calls such people the most wretched, as they are in deep pain, even if they hide it. He urges listeners to be straightforward and guileless, like a child or a true scientist, as this is the path to a resolved life.
