Verily the kindness that gazes upon itself in a mirror turns to stone, and a good deed that calls itself by tender names becomes the parent to a curse.
Kindness is the only service that will stand the storm of life and not wash out. It will wear well and will be remembered long after the prism of politeness or the complexion of courtesy has faded away.
If you develop a pure and sincere motivation, if you are motivated by a wish to help on the basis of kindness, compassion, and respect, then you can carry on any kind of work, in any field, and function more effectively.
That he who hath the loan of money has not repaid it, and he who has repaid has not the loan; but he who has acknowledged a kindness has it still, and he who has a feeling of it has requited it.
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.
