Laughter is one of the most divine experiences, but very few people really laugh. Their laughter is shallow. Either it is just intellectual, or just a facade, or just a formality, or just a mannerism.
If a man can laugh totally, wholeheartedly, not holding anything back at all, in that very moment something tremendous can happen because laughter, when it is total, is absolutely egoless and the only condition in which to know godliness is to be egoless.
There are many ways to be egoless, but laughter is the most beautiful.
