If you think that people should be nice to one another, then by
all means be nice. But when you project that belief onto the
people and the world around you as if it were an objective reality,
or worse still, as if it were their job to be nice to you, you put
yourself at odds with what is, and suffering will surely follow.
The truth is that you already are what you are seeking. You are looking for God with his eyes. I suggest you ask, "What's ultimately behind this set of eyes?" Turn around to see what is looking.
In liberation, you stand alone. You stand alone because you need no supports of any kind. You need no supports because you have realized that the very notion of a separate you no longer exists, that there is nothing to support, that the whole ego experience was a flimsy illusion. So you stand alone but are never, never lonely because everywhere you look, all you see is That, and you are That.
