titthāyatana: the 3 'articles of (heretical) belief'. which in A. III, 61 are declared as leading to inactivity, are: (1) the belief that all happiness and woe are produced through former kamma (prenatal actions; s. kamma); (2) that everything is uncaused; (3) that everything is created by God.

(1) is the teaching of Niggaṇṭha-Nāthaputta, the leader of the Niggaṇṭhas, the modern Jains. The fault with this doctrine is that it does not account for that happiness and woe which either are the result of the present life's good or bad action, or are associated with the corresponding action. (2) is the doctrine of Makkhali Gosāla; s. diṭṭhi.

 According to the above 3 doctrines, man is not responsible for his actions, so that all moral exertions become useless.
