I understand the definition of "invocation." That's why I said that I have spoken during the normal time of an invocation and explained what I said.
Of course I cannot invoke something I do not believe. I do believe, however, in the power of the human mind and in reason. If I am asked to offer an invocation, I do just what I said. And I've done it many dozens of times in a wide variety of situations.
So far, nobody's ever been bothered by it.
