I love, love idea of this term “man-cave”. If you twist it around enough and away from popular American culture, you arrive at most surprising things, as in somewhere there is “Vajrayogini Cave”, or a cave in which Milarepa meditated, or whole Maratica Cave where Guru Rinpoche the Padmasambhava meditated on Amitayus, demonstrating accomplishment of that practice.
Alas “man-cave” is usually in the basement of the house where one lives. ut ability to bring an occupation of life-long interest into that with healthy degree of solitude, that is just breathtaking.
Somewhere along the lines of the effort to make more room, while still in NYC I lost my easel. But then again, my best paintings were somehow painted on the floor.
