Moral training is one of the most important subjects of all ages, and plays a key role in providing mental health and human felicity; For this reason, one of the most important goals of the religious teachings is to adorn people with moral nurture, and divine prophets have been sent for this purpose. This issue is of prime importance in the era of Occultation and in respect to those who await Imam Mahdi (p.b.u.h). In fact, this issue lays the groundwork for the Imam's advent. This paper presents some approaches in the field of epistemology, with a descriptive-analytic library-based method. The outcome of the research indicates that moral education during the period of Occultation, relying on the field of cognition, has a constructive role in humanistic values. That is because the field of cognition is very important in the lives of people who wait for the Imam's appearance. The real expectant ones, because of their enthusiasm and love for the Imam of the Age, tend the Imam and make obedience to him at the forefront of their lives because of their right perception to high rank and essential position of the Imam in the Creation. The outcome of such a vision is to reach moral perfection and well-being in both this world and Hereafter.
