"there is no difficulty in finding out who is a third-class or fourth-class man, for one's position can be understood simply by this crucial test: is he or is he not a devotee of Krsna"

SB Canto 10.1 to 10.13

Anyone who is not a devotee of Kṛṣṇa and does not surrender to Kṛṣṇa must be considered narādhama, the lowest of men, and duṣkṛtī, one who always commits sinful activities. Thus there is no difficulty in finding out who is a third-class or fourth-class man, for one's position can be understood simply by this crucial test: is he or is he not a devotee of Kṛṣṇa?

SB 10.10.2-3, Translation and Purport:

Śukadeva Gosvāmī said: O King Parīkṣit, because the two sons of Kuvera had been elevated to the association of Lord Śiva, of which they were very much proud, they were allowed to wander in a garden attached to Kailāsa Hill, on the bank of the Mandākinī River. Taking advantage of this, they used to drink a kind of liquor called Vāruṇī. Accompanied by women singing after them, they would wander in that garden of flowers, their eyes always rolling in intoxication.

This verse mentions some of the material advantages afforded to persons associated with or devoted to Lord Śiva. Apart from Lord Śiva, if one is a devotee of any other demigod, one receives some material advantages. Foolish people, therefore, become devotees of demigods. This has been pointed out and criticized by Lord Kṛṣṇa in Bhagavad-gītā (7.20): kāmais tais tair hṛta jñānāḥ prapadyante 'nya-devatāḥ. Those who are not devotees of Kṛṣṇa have a taste for women, wine and so forth, and therefore they have been described as hṛta jñāna, bereft of sense. The Kṛṣṇa consciousness movement can very easily point out such foolish persons, for they have been indicated in Bhagavad-gītā (7.15), where Lord Kṛṣṇa says:

na māṁ duṣkṛtino mūḍhāḥ

prapadyante narādhamāḥ

māyayāpahṛta-jñānā

āsuraṁ bhāvaṁ āśritāḥ

"Those miscreants who are grossly foolish, lowest among mankind, whose knowledge is stolen by illusion, and who partake of the atheistic nature of demons, do not surrender unto Me." Anyone who is not a devotee of Kṛṣṇa and does not surrender to Kṛṣṇa must be considered narādhama, the lowest of men, and duṣkṛtī, one who always commits sinful activities. Thus there is no difficulty in finding out who is a third-class or fourth-class man, for one's position can be understood simply by this crucial test: is he or is he not a devotee of Kṛṣṇa?

Why are devotees of the demigods greater in number than the Vaiṣṇavas? The answer is given herein. Vaiṣṇavas are not interested in such fourth-class pleasures as wine and women, nor does Kṛṣṇa allow them such facilities.
