This is because the attainment of Buddhahood is the ultimate way of freeing all sentient beings from suffering. Though we need various skillful means to achieve this goal, the most needed is not merely to offer others money, good reputation, enviable position or to establish charities to feed or treat the poor.
Instead, the most meaningful method is to propagate Buddhadharma from which others may find out for themselves the true nature of life. This is the only way that can really benefit others.
