What/Who is 'Mara' in Buddhism? Is there any definition for 'Mara' in Buddhism? Islam has a concept called Shayṭān. They explain it as the devil inside a human (Islam explanation). There is something like this in Christianity too. Does Mara represent the bad side of humans or is Mara understood differently in Buddhism?
There are 5 kinds of Maras in Buddhism.


Khandha Māra - The five aggregates of clinging
Kilesa Māra - The defilements
Abhisankhāra Māra - The Karmic force
Maccu Māra - The death itself
Devaputta Māra - The god Mara who leads a faction in the Paranimmita-Vasavatti heaven.
