“We use the word “God” and rarely ask ourselves what is really meant by that word. We assume we understand the meaning of the word simply because we know how to use it in conventional contexts and grammatically correct sentences. But many of us have little conception of all that the idea contains and all the questions and answers that are part of it. And above all, many of us—at least it was so for me—are not aware of the inner experience that validates the idea, that shows the way towards impartial verification of the existence of that which we can justifiably and with good conscience call God.”
