There is no more self-contradictory concept than that of idle thoughts. What gives rise to the perception of a whole world can hardly be called idle. Every thought we have either contributes to truth or to illusion.
Gautama BuddhaTo avoid causing terror to living beings, let the disciple refrain from eating meat... the food of the wise is that which is consumed by the sadhus [holymen]; it does not consist of meat... There may be some foolish people in the future who will say that I permitted meat-eating and that I partook of meat myself, but... meat-eating I have not permitted to anyone, I do not permit, I will not permit meat-eating in any form, in any manner and in any place; it is unconditionally prohibited for all.
Gautama Buddha
