No enlightenment. No suffering. Makes sense, but then again, where would humanity be without enlightenment?
Thus, enlightenment = suffering? I guess it depends on what enlightenment is. If we take it as 'having light upon you', then it certainly IS suffering - the consequences of too much exposure to UV light can be skin cancers and melanomas, which are renowned for being painful and even life threatening Or if we take it as 'having knowledge', then sure - knowledge and fact don't bend to the whims of human fancy, and they can be brutally abrasive against things which would bring comfort to us. I guess you just gotta keep your chin up, no?
