But among the six acts (ordained) for him three are his means of
subsistence, (viz.) sacrificing for others, teaching, and accepting
gifts from pure men.
(Passing) from the Brahmana to the Kshatriya, three acts (incumbent
on the former) are forbidden, (viz.) teaching, sacrificing for
others, and, thirdly, the acceptance of gifts.
The same are likewise forbidden to a Vaisya, that is a settled rule;
for Manu, the lord of creatures (Pragapati), has not prescribed them
for (men of) those two (castes).
To carry arms for striking and for throwing (is prescribed) for
Kshatriya as a means of subsistence; to trade, (to rear) cattle, and
agriculture for Vaisya; but their duties are liberality, the study
of the Veda, and the performance of sacrifices.
Among the several occupations the most commendable are, teaching the
Veda for a Brahmana, protecting (the people) for a Kshatriya, and
trade for a Vaisya
