In our retreat this last Saturday we had a great conversation around Doubt and Faith. (Well, actually, it was pretty much just me talking about Doubt and Faith.)
Buddhism speaks of “verified faith.” You may hear a teaching about, say, how life is imbued with impermanence. Rather than take this on blind faith, you might actually explore and examine your inner experience to see if this is so. If this is verified in your experience, a sense of faith in this teaching becomes stronger.
All of this comes from your own investigation and experience, not solely from outside you.
Here are some great images you might enjoy that can shore up a sense of faith in our essential goodness.
