We will never regret the kind words spoken or the affection shown. Rather, our regrets will come if such things are omitted from our relationships with those who mean the most to us.
Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.
Humans — who enslave, castrate, experiment on, and fillet other animals — have had an understandable penchant for pretending animals do not feel pain. A sharp distinction between humans and 'animals' is essential if we are to bend them to our will, make them work for us, wear them, eat them — without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeelingly toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.
These are the roots of trees, O monks, these are empty huts. Meditate, monks, do not be negligent, or else you will regret it later. This is our instruction to you.
The superior man accords with the course of the Mean. Though he may be all unknown, unregarded by the world, he feels no regret - It is only the sage who is able for this.
Why was the human race created? Or at least why wasn't something creditable created in place of it? God had His opportunity. He could have made a reputation. But no, He must commit this grotesque folly - a lark which must have cost Him a regret or two when He came to think it over and observe effects.
There is a longing for a return to a time without the need for choices, free of the regret at the inevitable loss that all choice (however wonderful) has entailed.
It is chiefly, I regret to say, through journalism that such people find expression. I regret it because there is much to be said in favour of modern journalism. By giving us the opinions of the uneducated, it keeps us in touch with the ignorance of the community.
I know, that since life is our most precious gift, and as far as we can be absolutely certain, it's given to us to live but once, let us so live we will not regret years of useless virtue, and inertia, and timidity, and ignorance, and in our last moments we can say: 'All my life, all my conscious energies, have been dedicated to the most noble cause in the world, the liberation of the human mind and spirit - beginning with my own'.
It's not my story anymore: whenever I speak about the past now, I feel as if I were talking about something that has nothing to do with me. All that remains in the present are the voice, the presence, and the importance of fulfilling my mission. I don't regret difficulties I experienced; I think they helped me to become the person I am today, I feel the way a warrior must feel after years of training; he doesn't remember the details of everything he learned, but he knows how to strike when the time is right.
I don’t regret for a single moment having lived for pleasure. I did it to the full, as one should do everything that one does. There was no pleasure I did not experience.
