Post on his
website by Andrei
Volkov that discussed the term Kāmesumicchācāra, breaking it down into
it's constituent parts and discussing the full meaning of the word.
I have read these kinds of discussions often however the Pali suttas seem to only describe 'kāmesumicchācāra' as 'sexual' misconduct, since the only definition of the precept is about sex.
He is given over to misconduct in sexual desires: he has intercourse with such (women) as are protected by the mother, father, (mother and father), brother, sister, relatives, as have a husband, as entail a penalty, and also with those that are garlanded in token of betrothal.
For example, there are suttas for laypeople, such as AN 4.62, which discuss: "the proper season, on the proper occasions, for a householder partaking of sensuality (kāmabhoginā)".
As for the other precepts:
1st precept: 'Pānā means 'breath', such as in the term 'Ānāpānasati'. Atipāta = destruction.
2nd precept: adinn ādāna. ādāna' = seizing; grasping. 'adinna'= not given; not allowed.
4th precept: 'Musā' means 'falsehood; lie'. Therefore the 4th precept is only about lying or dishonest speech and is not about the harsh, divisive & frivolous speech that are included in the definition of Right Speech in the Noble Eightfold Path.
