To me, the essence of keeping the soul nourished is obedience to one's conscience. I don't think that the soul can be nourished unless people have a strong sense of conscience that they have educated and developed and soaked in the universal and timeless principles of integrity and service. This way, the individual's soul becomes part of the universal soul of service, contribution, and making a difference.
Stephen CoveyHumility is the mother of all virtues: the humble in spirit progress and are blessed because they willingly submit to higher powers and try to live in harmony with natural laws and universal principles. Courage is the father of all virtues; we need great courage to lead our lives by correct principles and to have integrity in the moment of choice.
Stephen CoveyOnce we are self-aware, we must choose purposes and principles to live by; otherwise the vacuum will be filled, and we will lose our self-awareness and become like groveling animals who live primarily for survival and propagation. People who exist on that level aren't living; they are "being lived".
