The lack of supply in humans lies in the physical, emotional, mental, and spiritual aspects. These four aspects become the language of needs and gaps in the survival of a human being. This is not just a matter of a lack of money or economic supply, which we often see as the most obvious thing to look for.
In fact, the lack of supply in human beings, when viewed through these four aspects, is so intertwined that it becomes the language of suffering, which is the source of deeper suffering than mere hunger or poverty.
All four aspects must have sufficient supply, and if asked which is most important, all four are equally essential. Because the physical aspect is essential for survival, the emotional and mental aspects are essential for living life, and the spiritual aspect is essential for giving meaning to life.
Thus, a form of strength will emerge to reinforce this, because when all of these aspects have sufficient or insufficient supply, a statement like a belief will emerge. Because once again, what can strengthen us the most is what is currently lacking within us.
