Some of the early greek thought systems share similarities with the eastern philosophy. Stoicism and buddhism seems to overlap in many aspects. Stoicism promotes the development of self-control as a means of overcoming destructive desires and emotions; the philosophy holds that becoming a clear and unbiased thinker allows one to understand the universal reason (logos). Buddhism is based on the realisation of the Four Noble Truths, and it promotes the Noble Eightfold Path that leads to true understanding of the reality and the universal truth.
“In the life of the individual man, virtue is the sole good; such things as health, happiness, possessions, are of no account. Since virtue resides in the will, everything really good or bad in a man’s life depends only upon himself. He may become poor, but what of it? He can still be virtuous. A tyrant may put him in prison, but he can still persevere in living in harmony with Nature. He may be sentenced to death, but he can die nobly, like Socrates. Therefore every man has perfect freedom, provided he emancipates himself from mundane desires.”
A History of Western Philosophy. Bertrand Russell, p. 254
(Causation) […] people are generally desirous. They cling obstinately to lives of wealth and honor, comfort and pleasure, excitement and self indulgence, ignorant of the fact that the desire for these very things is the source of human suffering. […] Ignorance is manifested in greed that fills the human mind. It comes from the fact that men are unaware of the true reason for the succession of things. p.84
(The Theory of Mind-only and the Real State of Things) People naturally fear misfortune and long for good fortune; but if the distinction is carefully studied, misfortune often turns out to be good fortune and good fortune to be misfortune. The wise man learns to meet the changing circumstances of life with an equitable spirit, being neither elated by success nor depressed by failure. p.122
