the 5 heinous ”actions with immediate destiny” are
parricide,
matricide,
killing an Arahat (Saint),
wounding a Buddha,
creating schism in the monks” Order.
In A.V. 129 it is said:
"There are 5 irascible and incurable men destined to the lower world and to hell, namely: the parricide," etc. About the 5th see A.X. 35, 38.
With regard to the first crime, it is said in D. 2 that if King Aja^tasattu had not deprived his father of life, he would have reached entrance into the path of Stream-entry (App.).
This term seems to be used for the first time in Kath. (190) of the Abh. Canon; the 5 crimes mentioned, however, are already enumerated and explained in the old Sutta texts (e.g. A.V, 129), as is to be seen from the main part of this work.
