This paper investigates the role of religion in developing human beings in the form of a Sufism-based education, one that is based on the pursuit for the perfect human. This investigation aimed to demonstrate that a human being is an "insan kamil," a person with seven levels of mental and moral development. Religion and spirituality play a critical role in maintaining mental and physical health according to recent studies. This study claims that natural perfection--which culminates in bodily rebirth, resurrection, and union with God--and the cultivation of one's soul are two forms of perfection pursued by humans. A person's free will determines the sort of existence that develops in the physical process between birth and death, and this is marked by the first stage of life. Sufis refer to people on this path of self-cultivation as "insan kamil" (flawless people). They are those on the route to God and a return to the real human condition. As a Muslim, you are considered "insan kamil" if you have understood that your inner essence is that of Allah. Such people are said to be a true human being, a manifestation of the attributes of Allah.
