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. In this connection, Śrīla Madhvācārya says:

aprayojana-pakṣaṁ na saṁśrayet

nāprayojana-pakṣī syān na vṛthā śiṣya-bandha-kṛt na codāsīnaḥ śāstrāṇi na viruddhāni cābhyaset

na vyākhyayopajīveta na niṣiddhān samācaret evam-bhūto yatir yāti tad-eka-śaraṇo harim

“There is no need to take shelter of unnecessary literature or concern oneself with many so-called philosophers and thinkers who are useless for spiritual advancement. Nor should one accept a disciple for the sake of fashion or popularity. One should be callous to these so-called śāstras, neither opposing nor favoring them, and one should not earn one’s livelihood by taking money for explaining śāstra. A sannyāsī must always be neutral and seek the means to advance in spiritual life, taking full shelter under the lotus feet of the Lord.”
