The thumb alone would convince me
In the absence of other proof, the thumb alone would convince me of God's existence.
I personally believe the noise pollution, both physically noise pollution, as well as our inner noise pollution, is probably one of the single biggest threats to our humanity. And to be able to quiet ourselves enough in whatever practice, and then in the fields of discovery of where we work or where we live, find quietude, so that the signal and antenna can even meet is, to me, the front line of the work. Because if we can't quiet ourselves, getting the instructions, knowing how to meet each other is actually impossible.
