Three causes of disturbing emotions

Three causes of disturbing emotions given in the Abhidharma are:

1. not having abandoned the latent tendencies or predispositions (nyon mongs pa’i bag la nyal ma spang),
2. coming into contact with a provocative object (nyon mongs skye ba’i yul nye bar gnas pa), and
3. incorrect thinking/unhelpful attitude (tshul zhin ma yin pa yid la byed pa)
