Although considered as one of the Hindu religions and despite some similarities, Jainism, due to its attitude towards soul and its origin, is placed somehow contrary to Hinduism. Jainism and Hinduism have many similar characteristic features, including the concepts of samsara, karma and moksha. However, Jain’s attitude to human nature and his final goal and the way to reach that goal distinguishes it from Hinduism. Despite huge complexities of Jainism, it can be said that soul (jiva) plays a critical role in this religion; respect to creatures, no matter in what rank they are (Ahiṃsā), is the main and fundamental rule of Jainism; this respect is derived definitely not from a materialistic aspect, but rather due to a soul which reaches a superior rank of human existence by passing through different worlds; therefore, Jainists, following specific ethical principles and going through severe physical austerities, as a result of which the effect of Matter (Ajiva) on the soul (jiva) is disappeared, can achieve the state of sincerity (Maqam e Kholus) and essence of being. This state has a godlike status in Jainism. However, achieving this feature will be examined by describing the issues relevant to this religion. Clearly, it will be explained by examining the concept of soul and its type and the relationship between soul/body and soul/deed, as well as the issue of incarnation and the way to salvation in this religion.
