The ego doesn't allow us to know what we lack. The ego operates on the scarcity principle meaning that we always have anxiety that we are inadequate or deficient in some way and so we spend our energy trying to soothe our anxiety by getting more. However, what we lack is God. We are suffering from the separation from God and from each other. Jesus tells us as much when he tells his followers that the way to the kingdom is "to love as I have loved."
What this eight principle points to is the observation that some of us have a more loving heart than others and those with a more loving heart are called to help those who are less loving. This is a temporary phenomenon until those with less love catch up with those with more love. Love is all around us. Tune in and then broadcast it as you go about your daily routine living with Love. This idea reminds me of the bumper sticker, "If you see someone without a smile, give him one of yours." Spiritual people are people of peace and joy.
