65 At all events, all he said, according to Onesicritus, tended to this, that the best teaching is that which removes pleasure and pain from the soul; and that pain and toil differ, for the former is inimical to man and the latter friendly, since man trains the body for toil in order that his opinions may be strengthened, whereby he may put a stop to dissensions and be ready to give good advice to all, both in public and in private; and that, furthermore, he had now advised Taxiles to receive Alexander, for if he received a man better than himself he would be well treated, but if inferior, he would improve him. Onesicritus says that, after saying this, Mandanis inquired whether such doctrines were taught among the Greeks; and that when he answered that Pythagoras taught such doctrines, and also bade people to abstain from meat, as did also Socrates and Diogenes, and that he himself had been a pupil of Diogenes, Mandanis replied that he regarded the Greeks as sound-minded if, but that they were wrong in one respect, in that they preferred custom to nature; for otherwise, Mandanis said, they would not be ashamed to go naked, like himself, and live on frugal fare; for, he added, the best house is that which requires the least repairs. And Onesicritus goes on to say that they inquire into numerous natural phenomena, including prognostics, rains, droughts, and diseases; and that when they depart for the city they scatter to the different market-places; and whatever they chance upon anyone carrying figs or bunches of grapes, they get fruit from that person as a free offering; but that if it is oil, it is poured down over them and they are anointed with it; and that the whole of a wealthy home is open to them, even to the women's apartments, and that they enter and share in meals and conversation; and that they regard disease of the body as a most disgraceful thing; and that he who suspects disease in his own body commits suicide through means of fire, piling a funeral pyre; and that he anoints himself, sits down on the pyre, orders it to be lighted, and burns without a motion.
