Stephen Covey talks about the 4 human needs -- Physical (To Live), Social/Emotional (To Love), Mental (To Learn), and Spiritual (To Leave A Legacy) in his book "First Things First". Here is an excerpt on what he says about Spiritual Needs:
"....the wisdom of literature of thousands of years of history repeatedly validates the reality that the greatest fulfillment in improving ourselves comes in our empowerment to more effectively reach out and help others. Quality of life is inside-out. Meaning is in contribution, in living for something higher than self. And the results of the illusion and the reality are as different as the Dead Sea -- a stagnant end in itself where there's no outlet and no life -- and the Sea of Galilee, where the waters flow on and nurture abundant life along the way."
"To Leave a Legacy is also by definition, interdependent. It's contributing to society, contributing in meaningful ways to the lives of others. The world we live in is the legacy of those who have gone before us. The choices we make in it create a legacy for those who will follow."
I have yet to see the WTS's teachings "nurture abundant life". I have experienced the legacy from the WTS. They have not embraced "True North Principles". When you ignore these, your legacy is one of destruction. My family is just one example of how the WTS does not work.
