The drawing mind relies on the idea that the brain (yes, we have heard that) is plastic and can transform itself.
I imagine that for those that would struggle to sit on a hard cushion, crosslegged, trying to silence the brain or for those that would scorn the experience of "savouring the raising", this is a good alternative.
Apparently the author hints the reader, the creative reader, without giving too many indications though, to "draw with your smell", "draw with your feet". This would take to the experience of distracting the criticizing mind, and to start experimenting new alternative ways of observing reality, of drawing and ultimately of thinking.

I have ordered the book, I liked the cover too (what counts if not the cover)
