In plain words
When Siddhārtha, sitting under the Bodhi tree at Bodh Gayā and practising tapas and dhyāna, had attained the state of full ripeness, some people gathered there and reviled the Buddha most basely. At this, the followers and disciples, blazing with anger: “Swami! Give us leave, and we will teach these people a fine lesson. The stick works tenfold. These fellows will never come to their senses until their backs are broken,” they asked; and the Buddha: “My dear ones! How much joy they are finding in reviling Me! Look! If you find joy in praising, they win their satisfaction by reviling. They cause Me no hurt at all; you must hold your anger in check and carry yourselves calmly. Hating no being — this very thing must be man's natural way of acting. This itself is the ideal of the great souls of Bhārata,” he said.
Those who cannot bear another's good may revile out of envy; the demon-hearted may revile by nursing the grudge ‘He is greater than I am’ and feeding their hatred. Or else, when what they wanted does not come to pass, and they do not examine themselves, they may lose their patience in disappointment and revile. Such people are of petty intellect; they take to base paths; if you deal with them and form ties with them, you yourselves will be badly soiled.
