We are all sādhus, actually, originally, because we are part and parcel of Kṛṣṇa, but in contact with māyā, we have become asādhu. Sādhu means who are pure devotees. Bhajate mām ananya-bhāk. That is sādhu. Otherwise there is no sādhu. The so-called sādhu, they are not sādhu. Sādhu means bhajate mam ananya-bhāk. Sādhur eva sa mantavyaḥ, bhajate mām ananya-bhāk (BG 9.30). So by chanting this Hare Kṛṣṇa mantra, even the lowest of the mankind, narādhamā, he can become a sādhu. "What is evidence how one can become sādhu simply by chanting?" Yes. Narottama dāsa Ṭhākura says, pāpī tāpī yata chilo, harināme uddharilo tāra sākṣi jagāi and mādhāi. Just see how Jagāi-Mādhāi became sādhu. Caitanya Mahāprabhu introducing this saṅkīrtana movement, He is making everyone sādhu. This is Kṛṣṇa consciousness movement. Everyone is becoming sādhu. Bhajate mām ananya-bhāk. So this avatāra, nāma-rūpe avatāra, there is no difference. Nāma-cintāmaṇiḥ-kṛṣṇaḥ caitanya-rasa-vigrahaḥ. The nāma is also vigraha, another form of the Lord, rasa-vigraha. So if we take shelter of this avatāra, rucy-avatāraiḥ... Every avatāra, every incarnation of Kṛṣṇa is very pleasing. Because Kṛṣṇa is the reservoir of all pleasure, therefore His avatāra... Just like Nṛsiṁhadeva, although He is very ferocious to asuras... They are disturbed. They are disturbing elements and they are disturbed. But Prahlāda Mahārāja is not disturbed. He's peaceful. So Lord's incarnation, either He is very ferocious or He's very kind, for the devotees there is no disturbance. Devotees are not disturbed, and the asuras are disturbed. So take shelter of the holy name of the Lord. Then disturbing condition of this material world will not touch you.
Ceto-darpaṇa-mārjanam bhava-mahā-dāvāgni-nirvāpaṇam (CC Antya 20.12). Bhava-mahā-dāvāgni-nirvāpaṇam. There is a blazing fire. That is the duty, that is the business of... Vande guroḥ śrī caraṇāravindam. How to extinguish the blazing fire of this material world—that is the duty. Every devotee, every pure soul, duty is how to extinguish the blazing fire. And that can be done only by pushing on this Kṛṣṇa consciousness movement. Otherwise it is not possible. Ceto-darpaṇa-mārjanam-bhava-mahā-dāvāgni-nirvāpaṇam śreyaḥ-kairava-candrikā-vitaraṇam... Śreyaḥ-kairava-candrikā. The ultimate benefit of life is compared with the moon. So spreading Kṛṣṇa consciousness means spreading the moonlight. Therefore we have named this temple Śrī Māyāpura-candrodaya. Śrī Caitanya Mahāprabhu is Gaura Hari, Māyāpura-cand... Caitanya-candra. Caitanya-candra anurāga. The Prabodhānanda Sarasvatī, this, kurutānurāga. Caitanya-candra-caraṇe kurutānurāga. Caitanya-candra-caraṇe kurutānurāga. Sādhava sakalam eva vihāya durāt caitanya-candra-caraṇe kurutānurāgam. This is the instruction of Prabodhānanda Sarasvatī, one of the great devotees of Lord Caitanya. So they are of the same opinion. There is no difference, opinion, between the modern devotee and the old devotee. A devotee is devotee, as there is no difference between modern gold or old gold. Gold is gold. So we should take the path of devotional service, following Prahlāda Mahārāja, and his prayers, his instructions are so valuable that even simply by reciting this Prahlāda Mahārāja's stotra, this stotra... This prayer of Prahlāda Mahārāja is very, very important. You read it carefully and try to understand. Even the most wretched demon can become a great devotee.
