"If this potential for unselfish joy is widely and methodically encouraged and developed, starting with the Buddhist child (or, for that matter, with any child) and continued with adults (individuals and Buddhist groups, including the Sangha), the seed of mudita can grow into a strong plant which will blossom forth and find fruition in many other virtues, as a kind of beneficial “chain reaction”: magnanimity, tolerance, generosity (of both heart and purse), friendliness, and compassion. When unselfish joy grows, many noxious weeds in the human heart will die a natural death (or will, at least, shrink): jealousy and envy, ill will in various degrees and manifestations, cold-heartedness, miserliness (also in one’s concern for others), and so forth. Unselfish joy can, indeed, act as a powerful agent in releasing dormant forces of the Good in the human heart."
