Yes indeed, Life is Complicated. The complexity of Life demands the experience of Peace and Harmony to bring together Whole Foods, Whole People, and Whole Planet. Without the experience of peace and harmony, there can be no experience of Life.
The idea of peace is always part of the idea of well-being and good health. The idea of perfect well-being also includes ideas of inner peace, tranquility, and harmony. The physical, mental, and social well-being are a part of man’s well-being in the environment, and community where he lives. To achieve perfect peace or Whole Peace, we must include the dimensions of the man’s moral, and spiritual well-being apart from the physical, mental, and social well-being. The aspects of external and internal or inner peace work together to contribute a Blissful Existence while man experiences Joy in his mind, and Love in his heart. Hence, peace is not mere absence of war and strife.
