Material affairs have herein been compared to an ocean of poison. They have been described in a similar way by Śrīla Narottama dāsa Ṭhākura in one of his songs:
saṁsāra-viṣānale, divā-niśi hiyā jvale,
juḍāite nā kainu upāya
"My heart is always burning in the fire of material existence. and I have made no provisions for getting out of it."

golokera prema-dhana, hari-nāma-saṅkīrtana,
rati nā janmila kene tāya
"The only remedy is hari-nāma-saṅkīrtana, the chanting of the Hare Kṛṣṇa mahā-mantra, which is imported from the spiritual world, Goloka Vṛndāvana. How unfortunate I am that I have no attraction for this."

(Srimad Bhagavatam------5:1:22-------purport).

The principles of the paramparā system were strictly honored in previous ages—Satya-yuga, Tretā-yuga and Dvāpara-yuga—but in the present age, Kali-yuga, people neglect the importance of this system of śrauta-paramparā, or receiving knowledge by disciplic succession. In this age, people are prepared to argue that they can understand that which is beyond their limited knowledge and perception through so-called scientific observations and experiments, not knowing that actual truth comes down to man from authorities. This argumentative attitude is against the Vedic principles, and it is very difficult for one who adopts it to understand that the holy name of Kṛṣṇa is as good as Kṛṣṇa Himself. Since Kṛṣṇa and His holy name are identical, the holy name is eternally pure and beyond material contamination. It is the Supreme Personality of Godhead as a transcendental vibration. The holy name is completely different from material sound, as confirmed by Narottama dāsa Ṭhākura: golokera prema-dhana, hari-nāma-saṅkīrtana. The transcendental vibration of hari-nāma-saṅkīrtanais imported from the spiritual world. Thus although materialists who are addicted to experimental knowledge and the so-called "scientific method" cannot place their faith in the chanting of the Hare Kṛṣṇa mahā-mantra, it is a fact that simply by chanting the Hare Kṛṣṇa mantra offenselessly one can be freed from all subtle and gross material conditions. The spiritual world is called Vaikuṇṭha, which means "without anxiety." In the material world everything is full of anxiety (kuṇṭha), whereas in the spiritual world (Vaikuṇṭha) everything is free from anxiety. Therefore those who are afflicted by a combination of anxieties cannot understand the Hare Kṛṣṇa mantra, which is free from all anxiety. In the present age the vibration of the Hare Kṛṣṇa mahā-mantra is the only process that is in a transcendental position, beyond material contamination. Since the holy name can deliver a conditioned soul, it is explained here to be sarva-mantra-sāra, the essence of all Vedic hymns.

(Sri Caitanya Caritamrta-------1:7:74-------purport).

Śrī Caitanya Mahāprabhu belongs to the spiritual world, and His methods for propagating the saṅkīrtana movement are also imported from the spiritual world. Śrīla Narottama dāsa Ṭhākura has sung: golokera prema-dhana, hari-nāma-saṅkīrtana, rati na janmila kene tāya. This states that the saṅkīrtana movement has nothing to do with this material world. It is imported from the spiritual world, Goloka Vṛndāvana. Narottama dāsa Ṭhākura laments that mundane people do not take this saṅkīrtana movement seriously. Considering the position of devotional service and the saṅkīrtana movement, Śrī Caitanya Mahāprabhu deemed the system of varṇāśrama-dharma to be material, although it aims at elevation to the spiritual platform. However, the saṅkīrtana movement can raise one immediately to the spiritual platform. Consequently it is said that varṇāśrama-dharma is external, and Caitanya Mahāprabhu requested Rāmānanda Rāya to proceed deeper into the matter and uncover the spiritual platform.
