Bhagavad Gita!

According to the Bhagavad Gita, the Caste systems flow smoothly in a certain path for each individual. For example, in the passage, it states, "As a man, casting off old clothes, puts on others and new ones" (The Bhagavad Gita). Anyway, between the teachings of Zarathustra and Confucius, there are various connections that can be made. In the teachings of Zarathustra and the Bhagavad Gita, there is the mention of a soul which is the connection of similarity between them. However, the difference is that in the Bhagavad Gita's teachings, everyone has to be detached from their desires such as winning, while in Zarathustra's teachings, people can enjoy life, but only in moderation. Also, in Zarathustra's teachings, there is a needing to save the soul, whereas in the Bhagavad Gita, it says that all souls of people are reincarnated into something different. With Confucianism and Bhagavad Gita, the connections are that they both believe in a certain way to live life effectively ("The Way" with Confucianism, while "Detachment" with Bhagavad Gita).  They contrast by exactly what people do to live their lives; Confucianism involved avoiding both religion and metaphysics, while the Bhagavad Gita greatly had to do with religion as its core element.
