It seems to me that faith is related to one’s own interaction with life. You have to look at life, you have to perceive it, understand it, correlate the understanding to interactions in different situations, and when the interactions confirm and verify the understanding that has taken place, there arises an awareness of truth which the interaction has caused. That awareness is then beyond doubt, beyond suspicion, beyond the argumentation of other people, beyond theories, dogmas and doctrines. Perhaps the word faith indicates the substance of that awareness.
