Dhammapada v. 116
We are familiar with the teachings that caution us against unwholesomeness. And we already know that it takes effort to be restrained. But here the Buddha is making a point which might not have occurred to us before: if we are tardy to do good, we are more likely to fall for the allure of the not-good; unwholesomeness increases its appeal. If we truly understand this, we see the wisdom of cultivating wholesomeness and the protection we are afforded.
