I don't believe there's anything in life you can't go back and fix. The ancient Vedas - the oldest Hindu philosophy - and modern science agree that time is an illusion. If that's true, there's no such thing as a past or a future - it's all one huge now. So what you fix now affects the past and the future.
In Hindu philosophy the whole creation is regarded as the Vishnu Lila, the play of Vishnu. Lila means dance or play. Also in Hindu philosophy, they call the world illusion; and in Latin the root of the word illusion is ludere, to play.
Monks, one thing, if practiced and made much of, conduces to great thrill, great profit, great security after the toil, to mindfulness and self-possession, to the winning of knowledge and insight, to pleasant living in this very life, to the realization of the fruit of release by knowledge. What is that one thing: It is mindfulness centered on the body.
To conclude, therefore, let no man upon a weak conceit of sobriety or an ill-applied moderation think or maintain that a man can search too far, or be too well studied in the book of God's word, or the book of God's works, divinity or philosophy; but rather let men endeavor an endless progress or proficience in both; only let men beware that they apply both to charity, and not to swelling; to use, and not to ostentation; and again, that they do not unwisely mingle or confound these learnings together.
Again men have been kept back as by a kind of enchantment from progress in science by reverence for antiquity, by the authority of men counted great in philosophy, and then by general consent.
Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.
He in whom the love of repose predominates will accept the first creed, the first philosophy, the first political party he meets — most likely his father's. He gets rest, commodity, and reputation; but he shuts the door of truth.
Every reader should ask himself periodically “Toward what end, toward what end?”—but do not ask it too often lest you pass up the fun of programming for the constipation of bittersweet philosophy.
More and more it seems to me that the philosopher, being of necessity a man of tomorrow and the day after tomorrow, has always found himself, and had to find himself, in contradiction to his today: his enemy was ever the ideal of today. So far all these extraordinary furtherers of men whom one calls philosophers, though they themselves have rarely felt like friends of wisdom but rather like disagreeable fools and dangerous question marks, have found their task, their hard, unwanted, inescapable task, but eventually also the greatness of their task, in being the bad conscience of their time.
But the idols of the Market Place are the most troublesome of all: idols which have crept into the understanding through their alliances with words and names. For men believe that their reason governs words. But words turn and twist the understanding. This it is that has rendered philosophy and the sciences inactive. Words are mostly cut to the common fashion and draw the distinctions which are most obvious to the common understanding. Whenever an understanding of greater acuteness or more diligent observation would alter those lines to suit the true distinctions of nature, words complain.
