This is what faith and wisdom can mean to us, the emotions and the thinking. When we cultivate both, we develop our faculties into powers. Harmonizing our emotional with our thinking capacities is the essence of harmonizing faith with wisdom. A powerful mind is a great asset, but only in conjunction with purified emotions. Faith is one such purified emotion.
Faith is much easier for people whose primary defilement is greed, rather than hate.
Faith arouses pleasant feelings, which is greed's direction. In this case, greed is an asset, although basically it is, of course, a negative characteristic. But if we use it in a positive way, we are engaged in a purification process, wanting that which is wholesome, which leads us to the supermundane. First greed opens up into faith, resulting in pleasant feelings. All are cravings, but they're going in the right direction, of using greed to get rid of greed.
