Fifteen minutes a day training the mind to work at optimum level? I fancy a bit of that. I thought, 'who are the Masters' at this? The Tibetan monks of course. I thought, I'll go there and do the job properly. Peace for twelve whole months! Just me, in a cave, no hassle! Perfect!It was okay for a while, although I don't suppose I'd recommend it to my grandmother, as she would have a bad time on Thursdays with no bingo.
