Words of wisdom are never abstract

“There is no rule of thumb for seizing opportunities, hitting off the right moment or adapting oneself to circumstances; it is all a matter of native wit.” (Liezi (Lieh Tzu), The Record of the Orally Transmitted Teachings, Nichiren Daishonin, as told by Nikko Shonin, p10) “The shrewd are good at weighing the future. The wise are good are preparing for the future.” (Huai-nan Tzu)) (World Tribune, 9/3/10, p4) It's only when there's something impossible that you want of much that you MUST have it and are racking your brains to make it reality that the meaning of these passages will become clear to you.
