"The Kabbalahists tell us that the 'upper force' doesn't listen to our words, but only responds to what's in our hearts."
I found this particular sentence really fascinating. A couple of things stood out for me regarding this sentence. One is that, we all know that words don't always convey what's in our hearts. We use them to mask our true thoughts or feelings or emotions. For example, when we tell others we're doing great, but really we feel crummy. The mentioning of our hearts also piqued my interest because it's a key component in Orthodox therapy; "Blessed are the pure in heart, for they shall see God.", and Psalm 50:6 "Behold, thou desirest truth in the inward parts: and in the hidden part (the heart) thou shalt make me to know wisdom."
Do you suppose that there is some truth to this understanding of prayer? That God typically responds to our hearts' condition rather than our words, which may not accurately convey our hearts?
