Part of the modern experience has to do with a highly consequential relationship with mental conceptions themselves. We've had several millenia to develop, archive, and reinforce concepts, and today they are highly compacted, continuous, and as a result, heavily freighted with emotion, and efficacious in producing emotion.
One feels greatly in accordance with one's conceptual framework that makes sense of the world, so that much phenomenological experience has to do with stable or shifting relationships with one's own conceptual understandings of a given state of affairs.
Change those conceptual frameworks, and you can change how you feel and behave in relation to the world. And when you feel and behave in the world differently, the series of concepts that may come up in the process may be altered in turn.
