Following the orders of Śrī Caitanya Mahāprabhu, one who preaches the glories of the Lord all over the world or all over the universe should be humbler than grass and more tolerant than a tree because a preacher cannot live an easygoing life. Indeed, a preacher must face many impediments. Not only is he sometimes cursed, but sometimes he must also suffer personal injury. For example, when Nityānanda Prabhu went to preach Kṛṣṇa consciousness to the two roguish brothers Jagāi and Mādhāi, they injured Him and made His head bleed, but nevertheless, He tolerantly delivered the two rogues, who became perfect Vaiṣṇavas.
