Actually our position is that we are always rendering service to someone, either to our family, country, or society. If we have no one to serve, sometimes we keep a pet cat or dog and render service to it. All these factors prove that we are constitutionally meant to render service, yet in spite of serving to the best of our ability, we are not satisfied. Nor is the person to whom we are rendering that service satisfied. On the material platform, everyone is frustrated.
The reason for this is that the service being rendered is not properly directed. For example, if we want to render service to a tree, we must water the root. If we pour water on the leaves, branches and twigs, there is little benefit. Similarly if the Supreme Personality of Godhead is served, all other parts and parcels will be automatically satisfied.
Consequently all welfare activities as well as service to society, family, and nation are realized by serving the Supreme Personality of Godhead.
It is the duty of every human being to understand his constitutional position with God and to act accordingly. If this is possible, then our lives become successful. Sometimes, however, we feel challenging and say, “There is no God,” or “I am God,” or even, “I don’t care for God.” But in actuality this challenging spirit will not save us.
God is there, and we can see Him at every moment. If we refuse to see God in our life, then He will be present before us as cruel death. If we do not choose to see Him in one feature, we will see Him in another. There are different features of the Supreme Personality of Godhead because He is the original root of the entire cosmic manifestation. In one sense, it is not possible for us to escape Him.
