In Taoism there is the concept of Jing-Qi-Shen (Essence-Vital Energy - Spirit), where Shen is the spirit that animates a corpse to make a living sentient being. I think this Shen is not the same as Soul which is supposed to be permanent entity which transmigrates (as in Hinduism).
Does this concept of Shen/Spirit find any place in Buddhism? People say that someone with penetrating sharp eyes has a strong spirit. This does make intuitive sense to me.
If there is a concept of Spirit in Buddhism what it is called and what is the theory? Dharmata? Prana?
Of course in some sects of Taoism, there is just not one spirit within a human body but many like "Po", "Li", "Hung" etc residing in different Organs while having different functions. I find this theory pretty fascinating and some of it does make sense to me. Is it contradictory to what Buddhism proposes?
AFAIK, even Buddhists do not deny that some human beings after death do not transmigrate immediately and their spirit gets stuck on Earth for a long time because of their attachment towards worldly life or the nature of their death (sudden accident for example). This perfectly fits with the traditions of ancestor worship found all over the world. After all, if the being gets a new birth somewhere, whom are their descendants worshiping anyway?
