Sutra: Be quick to do good. If you are slow, the mind, delighting in mischief, will catch you. ~The Dhammapada of Gautama the Buddha. CA. 500B.C.~
To do good means to share, to love, to serve, to be compassionate. And these are things that the miserly mind cannot do. But it will not say, "I don't wnat to do it," because that will not be very diplomatic. The diplomatice way is "tomorrow" -- postpone. Mind is a bureaucrat.
If you wait, the mind is going to give you suggestions, "Do this, do that." Do the good immediately -- why wait? And who knows? -- the next moment will never come; this may be the last moment! Act with that urgency, because death can overtake you any moment. Don't listen to the mind. Mind can go on and on postponing things and, before mind allows you to do anything, death may have knocked you down. Do good, because doing good immediately brings joy.
