Three sets of vows
The three vows (dom sum [Tib.]) are:
1) The vows of pratimoksha(skt.) or of individual liberation (sotar gyi dompa);
2) the Bodhisattva vows (changchub sempé dompa);
3) the samayas of the secret Mantrayana (sang ngag kyi dompa).
An alternative list is:
1) The vows of pratimoksha;
2) the dhyana vows; and
3) the vows of undefilement.
