The Eastern religions are the religions that originated in East, South and Southeast Asia and thus have dissimilarities with Abrahamic Religions that developed in the Middle East. This includes the East Asian religions, and Indian religions (Hinduism, Buddhism, and Jainism). Here is a list of all Eastern Religions included in Crusader Kings 3.
Buddhism follows the teachings of Gautama Buddha and subsequent “enlightened ones”, in order to overcome the suffering of existence, inflicted by the endless cycle of change through death and rebirth. Achieving enlightenment is the path to release from Samsara, into the non-existence of Nirvana.
Hinduism is a dharma, a way of life, that includes a multitude of gods and religious practices. Shared is the belief in samsara, the endless cycle of the soul’s continuous rebirth into the world, and moksha, the freeing from that cycle.
Jains seek to follow the twenty-four teachers, the thirtankaras, to leave the world’s eternal cycle of death and rebirth by attaining omniscience, Kevala Jnana. Non-violence and good lives is at the center of Jainism, for and the foremost prayer states that “the function of souls is to help one another.”
Following the teachings of Zoroaster, Zoroastrians believe in the lord of wisdom, Ahura Mazda, who is the source of all good, and who opposes falsehood, represented by Angra Mainyu. A Zoroastrian seeks the path of Truth through Good Thoughts, Good Words and Good Deeds.
Tao is the source, pattern, and substance from which all things exist. Living in harmony with the Tao leads to peace, contentment, and upon death, ascension to live within the Tao as an immortal spirit.
