A person’s life on this world is a type of spiritual sowing, as the verse states, ‘those who sow with tears will reap with joy’, because a person ‘sows’ good deeds in this world and reaps the benefit in the world to come. How big is our field? As long as the minutes we live. Who ever saw someone with vast lush fields as far as the eye can see who plows just the end of the field and is content with that? Surely such a person is a fool! Hashem gives us each as many minutes as we need to acquire what we need to acquire here, and no more. We should not waste our precious time foolishly, for we will be laughing stock forever for our imprudence, but rather ‘sow’ every inch of our ‘field’ carefully while we still have the strength and time.
