Ever since hearing Alan Watts, the British Zen Philosopher speak I lost my atheism and became interested in the fine and wonderful world of Cha'an (Zen) Buddhism. This has led to friendships with Galen Sharp, who was a pen-pal of Wei Wu Wei, and who also influenced GSB's mathematics, and now, I think, I'm fairly done with Zen because that was exactly what I was meant to see! Zen is the art of emptiness. ''Emptiness and nothing holy in it whatever!''' said Bodhidharma when asked what Zen is. Indeed, Terrence Grey, writing as Wei Wu Wei, wrote a book called ''Why Lazarus laughed'' and dying in Monaco married to a Russian princess at the age of 91, he was most certainly laughing! So what is the joke that Made Lazarus Laugh?  Here, Cha'an differs from traditional Buddhism which has a series of rituals and methods one needs to achieve it. Cha'an on the other hand is against practice and says that all the answers are within oneself, if we would only learn how to empty. Hence, Terrence Grey could be a good Buddhist and live in Monaco, and all the rest. Therefore, it seems reasonable we discuss how to empty and for  that I discuss the ''Heart Sutra'' which one Cha'an master said is about how to empty to see if we get anywhere on this journey. ''Form is void'' and ''void is form''. ''Form is nothing but void (emptiness) and ''void is nothing but form''. Apart from void there is no form and apart from form there is no void'', the Heart sutra concludes. So, if we look closely we see that there is no emptying emptiness, but, rather, there is just emptiness. In other words, as Laws of Form explains so well, there is no emptying emptiness ''Emptiness is just overboard with everything'' (Wei Wu Wei in The Tenth Man) or as was said to him by a Cha'an abbott ''Empty EVERYTHING''. So, in reality, there is no perpetual regression, there is just absolute absence, and the intersection between absolute absence and absolute presence of absence is the business of Zen. And if, we were to see that, profoundly, that in GSB's language, ''the first distinction, the mark and the observer are not only interchangeable, but, in the form, identical'' we too would get the joke that made Lazarus laugh! And as I've always felt myself to be ''getting the joke that made Lazarus laugh'' I think this would make a great subject for a book - I don't know why I've always got the joke that made Lazarus laugh, but how entertaining would a book be about someone who did? I hope you enjoyed reading this, and tune in for my book, haha!
