"So there are these snakelike persons, they are envious about our movement; they are opposing. That is the nature. Prahlāda Mahārāja also was opposed by his father, what to speak of others. These things will happen, but we should not be disappointed, as Prahlāda Mahārāja never became disappointed although he was teased in so many ways. He was also served with poison, he was thrown amongst the serpents and he was thrown from the hill, he was put under the feet of elephant. In so many ways put... Therefore Caitanya Mahāprabhu has instructed us that 'Do not be disappointed. Kindly forbear.' Tṛṇād api sunīcena taror api sahiṣṇunā (CC Adi 17.31): be tolerant more than the tree. I mean to say, one shall be meek and humble more than the grass. These things will happen. In one life if we execute our Kṛṣṇa consciousness attitude, even there is suffering little, don't mind. Go on with Kṛṣṇa consciousness. Don't be disappointed or hopeless, even there is some trouble. That is encouraged by Kṛṣṇa in Bhagavad-gītā, āgamāpāyino 'nityās tāṁs titikṣasva bhārata (BG 2.14): 'My dear Arjuna, even if you feel some pain, this bodily pain, it comes and goes. Nothing is permanent, so don't care for these things. Go on with your duty.' This is the instruction of Kṛṣṇa. Prahlāda Mahārāja is the practical example, and our duty is to follow the footprints of such person like Prahlāda Mahārāja."
