Yama

(2) In the ashtanga (“eight-part”) yoga first
codified by Patanjali (1st c. C.E.?), yama
(“restraint”) is the first and most basic of
the eight constituent elements of yoga
practice. Patanjali lists these as five:
abstaining from harm to other living
things (ahimsa), abstaining from theft,
truthfulness, celibacy (brahmacharya),
and abstaining from avarice. These can all
be characterized as “restraints” because
their intent is negative—they do not call
for positive actions as much as they entail
refraining from certain thoughts or actions
deemed especially injurious.
