The importance of complete and unrestrained trust, is in two directions. The first is the complete trust, that should it be given upon a romantic partner, one has a very broad chance of developing a wonderful relationship. The second is the complete trust, that should it be given upon a romantic partner, though the relationship fails, then from that complete trust, there is the most pain. From the most pain, the greatest of lessons are learned through it. From complete trust, success. Or, from complete trust, failure. Whichever occurs, we benefit.
