Acharya Prashant explains that the mind operates by looking at the world, perceiving diversity, discriminating between various things, and then picking one option, believing it to be better than the rest. This process of seeing diversity is what bewitches the mind, leading it to form likes and dislikes. The mind then gets caught in a cycle of chasing certain things and dropping others, establishing a hierarchy where one thing is considered higher than another, which fuels the continuous pursuit of the next attainment. This very functioning of the mind is what causes it to suffer. The choices it makes, based on the belief that one object is superior to another, are the root of this suffering. The speaker states that the objective of the Upanishads is to bring freedom from this suffering. The Rishis speak not merely to calm the mind, but to guide it to a point of wisdom where it can recognize its own follies and flawed processes. Suffering arises when one perceives distinctiveness or variety, which leads to feelings of incompleteness, insecurity, and the fear of losing what has been attained. This is because the world, as perceived through the senses, is fundamentally a world of diversity. The world is nothing but the diversity that one sees. In response to a question about seeing mental objects like happiness and sadness as one, Acharya Prashant affirms that it is possible if one is neither repulsed by nor enamored with them. He clarifies that spirituality is not about abandoning these dualities but about welcoming them without resistance, expectation, or attachment. For instance, happiness can be welcomed as a guest, and so can sadness. One should not make emotions like happiness or sadness special. If happiness is not special, it can be a delight. Similarly, if sadness is not made special, one can carry it lightly. Tears should be allowed to be just tears, without holding a great meaning, and then one can cry freely. Tears often erupt from a suppressed state because of the fear of sadness. The statement 'all is one' refers to the subject, the experiencer, not the objects. If one still experiences things differently based on desire, then 'all is one' is not yet a realized truth for them.
