Pain in life is inevitable but suffering is not. Pain is what the world does to you, suffering is what you do to yourself [by the way you think about the 'pain' you receive]. Pain is inevitable, suffering is optional. [You can always be grateful that the pain is not worse in quality, quantity, frequency, duration, etc]
When a man venerates those worthy of veneration, be they Buddhas or their disciples, who have transcended all obstacles and passed beyond sorrow and tears - venerating such as these, whose passions are extinguished and for whom there is no further source for fear, no one can calculate how great his merit is.
If for just the time of a finger-snap a monk produces a thought of loving-kindness, develops it, gives attention to it, such a one is rightly called a monk. Not in vain does he meditate. He acts in accordance with the master's teaching, he follows his advice. How much more so if he cultivates it.
The one who wanders independent in the world, free from opinions and viewpoints, does not grasp them and enter into disputations and arguments. As the lotus rises on its stalk unsoiled by the mud and the water, so the wise one speaks of peace and is unstained by the opinions of the world.
The calmed say that what is well-spoken is best; second, that one should say what is right, not unrighteous; third, what's pleasing, not displeasing; fourth, what is true, not false.
The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly. There are only two mistakes one can make along the road to truth; not going all the way, and not starting.
Do not overlook tiny good actions, thinking they are of no benefit; even tiny drops of water in the end will fill a huge vessel. Do not overlook negative actions merely because they are small; however small a spark may be, it can burn down a haystack as big as a mountain.
He who lives with his senses well controlled, moderate in his food and drink, he will not be overthrown, any more than the wind throws down a rocky mountain.
