Rejoicing is one of the most important qualities to cultivate. Chagdud Rinpoche teaches us in simple but profound manner:
“Rejoicing means taking pleasure in others’ good fortune. This doesn’t have to be anything grand. If we see someone resting for a moment in a comfortable spot, drinking cool water or enjoying the sun on her face, we rejoice in her happiness and wish that it might increase. We pray that by the power of our wishes, prayers, and pure heart, her happiness will grow unceasingly. Whether it is someone’s moment in the sun, new clothes, nice car, or winning lottery ticket, we are happy for her. We don’t give in to envy, thinking, “I wish I had a red car like that one.” Nor are we resentful, wondering, “Why does she get to drive around in such style?” When we truly rejoice, we leave no room for jealousy, competitiveness, or self centeredness. In fact, rejoicing in the happiness of others is the antidote to jealousy.
