the difference between "life" and "death" is greater (many would even argue significantly greater) than the difference between "different" and "two aspects of".
but I suppose I have also wound up believing that "everything" and "nothing" are more similar than one would initially guess. though not as similar as life and death.
but it's really about realizing and acknowledging a separation between what we are, our language, and the way in which the elements of language (symbols-vocabulary) are representations distinct from what they represent, with this, one can realize that life and death, while distinct concepts within language, are in fact aspects of a whole which cannot be logically fitted into languages such as ours.
