Worldly talks and literatures fit for crows.

Those who are sat are thus transcendentalists advanced in spiritual life, and when they hear questions from those who want to understand spiritual life, they become very happy. Transcendentalists are not interested in worldly talks. Indeed, worldly talks are very disgusting to them, and they avoid the company of those who talk about nonsensical worldly affairs. Sri Chaitanya Mahaprabhu advised His disciples: gramya-katha na shunibe. The word gramya refers to that pertaining to one's village, society or neighborhood. People are interested in talking about gramya-katha. Newspapers, for instance, are filled with gramya-katha. There is no spiritual understanding in them. In the United States there are many newspapers, and simply to publish the New York Times many trees have to be killed. Now there is a paper scarcity. Why are they uselessly killing trees just for gramya-katha? They are only interested in making a profit. There is, however, another kind of katha—krishna-katha [talks or literature pertaining to Krishna]. There are literatures which may be nicely presented from the literary point of view, but if there is no glorification of the Supreme Lord, they are useless.

na yad vachash chitra-padam harer yasho
jagat-pavitram pragrinita karhichit
tad vayasam tirtham ushanti manasa
na yatra hamsa niramanty ushik-kshayah

"Those words which do not describe the glories of the Lord, who alone can sanctify the atmosphere of the whole universe, are considered by saintly persons to be like unto a pilgrimage for crows. Since the all-perfect persons are inhabitants of the transcendental abode, they do not derive any pleasure there." (Srimad-Bhagavatam 1.5.10)

Worldly literatures are like places where crows take pleasure. In the bird society, there are crows and swans, and crows are interested in places where filthy things are thrown. However, swans prefer nice clear water with lotus flowers, and it is in such places that they take their pleasure. Similarly, there are men who are like crows and men like swans. That is a natural division. According to an old English proverb, Birds of a feather flock together. Crows mix with crows, and swans mix with swans. Since devotees are like swans (hamsas), a most advanced devotee is called paramahamsa. The paramahamsas are not interested in subjects fit for crows. A person who is interested in inquiring about transcendental subjects, krishna-katha, makes a paramahamsa very glad.
