PROUT holds that human beings have a spiritual nature. They have needs that cannot be possibly satisfied with material objects. The human have needs that cannot be possibly satisfied with material objects.
The human thirst for happiness is infinite, but material things are all infinite; hence they can never quench the human thirst. Human beings all seek unlimited joy, but material objects, being limited, can never offer that.
The limited cannot yield the unlimited. Only an infinite entity can satisfy the infinite human hunger for enjoyment. Spiritual activity is simply a pursuit of the infinite entity.
The way PROUT sees it, spiritual needs are an integral part of human nature.
