"We have to go from country to country, town to town, city to city, village to village, to enlighten them to become Kṛṣṇa conscious. That is sādhu's duty. Those who are preachers, they are better sādhu than those who have gone to Himalaya. The sādhus who have gone to Himalaya for his personal benefit, that is also good, but those sādhus who are preaching and facing so many difficulties, so many opposing elements, they are better sādhu. They are better sādhu. They are fighting for Kṛṣṇa's sake. So kāruṇikāḥ, because they are more compassionate. One sādhu has gone to Himalaya, sitting there in a secluded place not to be bothered by any asādhu. That is also nice, but that is personal interest. But those sādhus are not gone to Himalaya but have left Vṛndāvana, easy life, and gone to fight to the world, they are better sādhu. That is the opinion of Kṛṣṇa. Ya idaṁ paramaṁ guhyaṁ mad-bhakteṣv abhidhāsyati (BG 18.68). Na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ (BG 18.69). Those who are preaching the message of Bhagavad-gītā, facing many opposing elements, many difficulties, Kṛṣṇa says, na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ: 'Nobody is dearer than him.' So if you want to become very quickly under the recognition of Kṛṣṇa, then every one of you become a preacher of Kṛṣṇa consciousness. That is the message of Caitanya Mahāprabhu."
