With a smile (which presumably you once knew), your whole world will open up like the sun coming out, as this is the living organic bridge between human beings, all of whom are individual with their own subjective and unique experience, all of whom are probably in some way suffering, at least subliminally, and all of whom, in a sense, are all one body, as when a universe of surrounding people starts kind of working together, something very interesting is happening. Now this perspective is a pristine as a math formula, but in order to get the gist of it it is necessary to use the functions in a new way, just like when learning to ride a bicycle....so here is something to ponder in the deep dark of the night before you fall asleep, and at other times, too, but, as someone en this thread wrote, you should only do it if you want to....so....or should it be put "sew" or "sow"??. the mathematics of a smile that is not contrived but arises naturally...so how does it arise and what is function of it?...a new kind of math:-)
You are very young and a whole world of discovery and learning is ahead for you....
