I think of it like this: for psychedelics, the change to your brain chemistry is like changing the hardware architecture leading to changes in software behaviour. The fundamental processes of thought in your mind work differently and so the psychological responses you have to everyday sensory stimulus are completely changed in unexpected ways and you can reach conclusions and insights in thought that you hadn't before. This may be temporary but the experience does change how you understand things once you return to normal brain chemistry function. The simple fact of knowing and experiencing how broad the space of modes is in which your consciousness could operate is very powerful in my opinion.
