Much of the seeking after truth fails because we seek it as a human beings seeking to find something. Truth is not something to be found or known in any human sense of the word. A man who seeks to find the truth is like a man who is searching his dream trying to find the room in which he is asleep having the dream.
No amount of self reflection can help us find the “I” in us; it is never there. The “I” is never found by seeking because it is the very thing doing the seeking. When we cannot find something we are looking for it doesn’t necessary mean that it is not there; it could also be that what we are looking for is either ourselves or something already in our possession. But if it were never there to begin with, neither with us nor elsewhere, then how on earth did we come to think or talk about it, let alone seeking it?!
If the consciousness of the atheist cannot find God anywhere it could be because God is the one providing the light of his consciousness!
Knowledge of truth is not a human possibility; our humanity is itself the very thing that keeps us from knowing the truth.
One may even say that to know the truth is to know that there is nothing to know, hence nothing to seek, and hence nothing to lose.
