They happen because of our karma and our choices our desires and our habits. They r accomplished because of desire. However, many things happen. Many things r accomplished. Not the least of which r saints. They r created also. But they were not touched by these things. This was not their purpose. Their purpose was to love God and give that love to others. We spend time with those who help us accomplish certain desires and then those desires r exhausted so we must move on. Others will b there to assist us. We must b receptive when they come or loose the opportunity that we have also created. Ours effort is small compared to the grace that is added.
