Yet, in the Tantric and Classical view, art was a way that ordinary people can connect to wisdom. No mystical experiencies or psychedelic substances necessary.

What's amazing to me about Christopher Alexander and his work is that he's able to describe the process of generating such art (in the form of architecture) to ordinary people, using plain, relatable language. The links I posted in the earlier comment are examples.

In other words, you don't need to be someone with a rare skill.
