Shundo David Haye – Zen Priest

‘A Zen student should try to do one thing at a time. If you search for an article in your desk, you should push back the drawer that does not serve you and open the next. Each drawer contains something of importance, but if the article is not there, the other things have nothing to do with you at the moment. Would you leave all the drawers open or empty them all on the floor? Yet that is exactly what many people do with their mental objects. Those who eat candy while reading or listen to the radio while writing are likely to stray from the Zen spirit.’ (Commentary on the Iron Flute)

I feel like Senzaki would have given phones short shrift.
