Unhappiness is like a mental mouse infestation. The solution is to purge the mind of every wrong idea and negative emotion. Be like Bruno the cat. He’s sprawled out, watching. Mice aren’t fools.
Mindfulness is a schizophrenic kind of word. It identifies a problem (a full to overflowing mind) while citing itself as the solution.
Wisdom is the flower of an empty mind, not a full one.
