Kleshas are part of Buddhism.
Buddhism . In Theravada the ultimate goal is the cessation of the kleshas and the attainment of the sublime state of Nirvana , achieved by practicing the Noble Eightfold Path ( also known as the Middle Way ) , thus escaping what is seen as a cycle of suffering and rebirth . Kleshas ( [ क्लेश , kleśa ] किलेस kilesa ; ཉ ན མ ངས nyon mongs ) , in Buddhism , are mental states that cloud the mind and manifest in unwholesome actions . In the contemporary Mahayana and Theravada Buddhist traditions , the three kleshas of ignorance , attachment , and aversion are identified as the root or source of all other kleshas .
