When a philosopher has toothache, he may be in possession of all the knowledge there is, but his realization is that of tooth-ache. When a man is happy, his knowledge may cover all possible misery, but his realization is the exact opposite of his knowledge. Knowledge is always of what is, at the moment, non-being. Realization is always, for the time being, isolation both from what has been, what is to be, and equally from all that is not-self. Knowledge is always relative, always incomplete of necessity, because of its inherent duality.
Realization is always absolute because in unity there can be no sense of relativity.
Conscious realization of all Life is the goal of evolution.
