The present generation is benefiting from the various endeavors of past generations. Certainly there are countless numbers of things which can be classified as unseen blessings. And these are the ones that we take for granted every day, for we cannot see and feel them directly. Therefore, when we trace the causes of our own existence, we come to the realization that there are innumerable indirect causes from which we are benefiting.
