The symptoms of a sadhu are that he is tolerant, merciful and friendly to all living entities. He has no enemies, he is peaceful, he abides by the scriptures, and all his characteristics are sublime. Because Narada Muni is the most elevated of sadhus, devotees, to deliver Prajapati Daksa he silently tolerated the curse. Sri Caitanya Mahaprabhu has taught this principle to all His devotees:

One should chant the holy name of the Lord in a humble state of mind, thinking oneself lower than the straw in the street; one should be more tolerant than a tree, devoid of all sense of false prestige and should be ready to offer all respects to others. In such a state of mind one can chant the holy name of the Lord constantly. Following the orders of Sri Caitanya Mahaprabhu, 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 Nityananda Prabhu went to preach Krsna consciousness to the two roguish brothers Jagai and Madhai, they injured Him and made His head bleed, but nevertheless, He tolerantly delivered the two rogues, who became perfect Vaisnavas. This is the duty of a preacher. Lord Jesus Christ even tolerated crucifixion. Therefore the curse against Narada was not very astonishing, and he tolerated it.
