The three marks of existence are vital teachings that lie at the basis of being human. This was one of the first teachings the Buddha proposed. The three marks of existence describe human life being characterised in 3 main sections; Anicca, Anatta and Dukkha.
Anicca proposes that nothing lasts forever and everything changes; impermanence. The Buddha taught that no one should grow attached to other things as they will cease to exist. Secondly, the literal definition of Anatta means ''no soul/no self''. This idea is based of Anicca suggesting that nothing is permanent and for this reason Buddha rejects any possibilities of having a soul. Conversely, he explained the body to be made up of 5 parts; ''skandhas''. Finally, the Dukkha (unsatifactoriness of life) implies that suffering is mainly caused by people's unrealistic expectations. Dukkha derives from selfishness.
