三界:

(1) 欲界，即具有财欲、淫欲、情欲、色欲、食欲等有情所居之世界。上自第六他化自在天，中包括人界之四大洲，下至无间地狱等二十处；因男女参居，多诸染欲，故称欲界。

(2) 色界，色为变碍之义或示现之义，乃远离欲界淫、食二欲，而仍具有清净色质等有情所居之世界。此界在欲界之上，无有欲染，亦无女形，其众生皆由化生；其宫殿高大，系由色之化生，一切均殊妙精好。以其尚有色质，故称色界。此界依禅定之深浅粗妙而分四级，从初禅梵天，终至阿迦腻吒天，凡有十八天。

(3) 无色界，唯有受、想、行、识四心，而无物质之有情所住之世界。此界无一物质之物，亦无身体、宫殿、国土，唯以心识住于深妙之禅定，故称无色界。此界在色界之上，共有四天（空无边处天、识无边处天、无所有处天、非想非非想处天），又称四无色、四空处。

此三界之果报虽有优劣、苦乐等差别，但属迷界，系众生生死轮回之趣，故为圣者所厌弃。

<法华经·譬喻品>：三界无安，犹如火宅；众苦充满，甚可怖畏。
又《化城喻品》：能于三界狱，勉出诸众生。即劝三界诸有情莫以三界为安，当勤求解脱。

如来在世间，不言有与无；如来涅盘后，不言有与无。

不经一事不长一智，智慧是从人与事之间磨练出来的。

by 证严法师

人类的感官──眼、耳、鼻、舌、身、意，每天总是不断的向外去攀缘，对于外在的世界虚妄分别，因此产生了许多烦恼。如果我们能够一切返求自心，而不让此心随境而转，则不当看的不看，不当听的不听，不当说的不说。这就等于孔子说的：“非礼勿视，非礼勿听，非礼勿言，非礼勿动。

Anger needs no training to grow. On the relative level, compassion requires training. Relative compassion is like an illusion, but a good illusion that causes other illusions to dissipate.

by Yongey Mingyur Rinpoche

We work on ourselves in order to help others, but also we help others in order to work on ourselves.

by Pema Chodron

All the peace and happiness of the whole globe,
the peace and happiness of societies,
the peace and happiness of family,
the peace and happiness in the individual person's life,
and the peace and happiness of even the animals and so forth,
all depends on having loving kindness toward each other.

When you cherish others, all your wishes are fulfilled

Living your life for others, cherishing them with loving kindness and compassion is the door to happiness, the door to enlightenment.

by Lama Zopa Rinpoche

三法印 :

诸行无常、诸法无我、涅槃寂静。

Another time I was teaching in Ukraine and stopped in Kiev for the day to see a friend of the man who was translating for me. The food she offered us was several varieties of potatoes. That’s all she had. But we were her guests so she pulled out some chocolate she had been saving and shared it with us. Although she had little money, when we got to the train station she got some baked goods for us to have on the train.

I had a maroon cashmere sweater which I loved – talk about the eight worldly concerns! On the way to the train station the thought came into my mind to give Sasha my sweater. And instantly another thought said, “No! Get that idea out of your mind, it’s unreasonable and stupid!”

There I was, someone from a wealthy country, I was only going to be there another couple of weeks, it was springtime, I didn’t really need the sweater and I could get another sweater (perhaps not a beautiful cashmere one,) back in the States.

But I was so attached to that sweater. My mind was so painful and an internal civil war waged the whole ride to the station, “Give her the sweater! No, you need it. Give it to her. No, she won’t like it,” on and on.

Just before the train left the station, I gave her the sweater, and I’ll never forget the look of joy on her face. And to think my attachment and miserliness almost sabotaged that!

Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.

 by Dalai Lama

戒的意义，就是止恶生善的意思，止除十恶五逆的罪恶，如防流水，似护眼珠，滋长善法，是名戒义。

by 虚云法师

Whenever we feel that we are definitely right, so much so that we refuse to open up to anything or anybody else, right there we are wrong. It becomes wrong view. When suffering arises, where does it arise from? The cause is wrong view, the fruit of that being suffering. If it was right view it wouldn't cause suffering.
