Returning to Our Natural Consciousness
117
“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 place of pilgrimage for crows. Since the all-perfect persons are inhabitants of the transcendental abode, they do not derive any pleasure there.”
tad-vāg-visargo janatāgha-viplavo 
    yasmin prati-ślokam abaddhavaty api 
    nāmāny anantasya yaśo 'ṅkitāni yat 
    śṛṇvanti gāyanti gṛṇanti sādhavaḥ
“On the other hand, that literature which is full of descriptions of the transcendental glories of the name, fame, forms, pastimes, etc., of the unlimited Supreme Lord is a different creation, full of transcendental words directed toward bringing about a revolution in the impious lives of this world’s misdirected civilization. Such transcendental literatures, even though imperfectly composed, are heard, sung, and accepted by purified men who are thoroughly honest.”
Any literature that has no connection with God is just like a place where crows take enjoyment. Where do crows enjoy? In a filthy place. But white swans take pleasure in nice clear waters surrounded by gardens. So even among animals there are natural divisions. The crows will not go to the swans, and the swans will not go to the crows. Similarly, in human society there are men who are like crows and men who are like swans. The swanlike men will come to centers of Kṛṣṇa consciousness, where everything is clear, where there is good philosophy, good transcendental food, good education, good intelligence—everything good—whereas crowlike men will go to clubs, parties, naked dance shows, and so many other such things.
So the Kṛṣṇa consciousness movement is meant for swanlike men, not for men who are like crows. But we can convert the crows into swans. That is our philosophy. Those who were crows are now swimming like swans. That is the benefit of Kṛṣṇa consciousness.
The material world is the world where swans have become crows. In the material world the living entity is encaged in a material body, and he tries to gratify his senses in one body after another. But the reestablishment of  dharma  will gradually turn crows into swans. For example, a man may be illiterate and uncultured, but he can be converted into an educated, cultured man by training.
