SB Canto 7
SB 7.13.7, Purport:
A person desiring to advance in spiritual understanding should be extremely careful to avoid reading ordinary literature. The world is full of ordinary literature that creates unnecessary agitation in the mind. Such literature, including newspapers, dramas, novels and magazines, is factually not meant for advancement in spiritual knowledge. Indeed, it has been described as a place of enjoyment for crows (tad vāyasaṁ tīrtham). Anyone advancing in spiritual knowledge must reject such literature. Furthermore, one should not concern oneself with the conclusions of various logicians or philosophers. Of course, those who preach sometimes need to argue with the contentions of opponents, but as much as possible one should avoid an argumentative attitude.
CC Adi 7.74, 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-saṅkīrtana is 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 Lectures
Lecture on CC Madhya-lila 20.98-102 -- April 27, 1976, Auckland, New Zealand:
Prabhupāda: No, no. First of all answer this. Suppose there is a big meeting going on, and some big man is present. Suppose the President is there. Can you talk with him? Why? Why you cannot talk? For talking we think you require some qualification. It is not that He's so cheap that you talk with Kṛṣṇa immediately.
- ataḥ śrī-kṛṣṇa-nāmād
- na bhaved grāhyam indriyaiḥ
- sevonmukhe hi jihvādau
- svayam eva sphuraty adaḥ
- [Cc. Madhya 17.136]
So if you accept Kṛṣṇa as the Supreme Lord, then you have to qualify yourself to talk with Him.
Guest: By His grace, Kṛṣṇa will show Himself to you.
Prabhupāda: Yes. If you read Kṛṣṇa book and if you believe, then you see Kṛṣṇa. He's not different from the book.
Guest: But we could read words till the cows come home. What good is that going to do?
Devotee: You have to accept what you read. You can't read with an argumentative attitude, or you can't ask questions in an argumentative attitude. You'll never learn.
