There are five branches of irreligion, appropriately known as irreligion [vidharma], religious principles for which one is unfit [para-dharma], pretentious religion [ābhāsa], analogical religion [upadharma] and cheating religion [chala-dharma]. One who is aware of real religious life must abandon these five as irreligious.
Any religious principles opposed to the principle of surrendering to the lotus feet of the Supreme Personality of Godhead, Kṛṣṇa, are to be considered religious principles of irregularity or cheating, and one who is actually interested in religion must give them up. One should simply follow the instructions of Kṛṣṇa and surrender unto Him. To do this, of course, one needs very good intelligence, which may be awakened after many, many births through good association with devotees and the practice of Kṛṣṇa consciousness. Everything but the principle of religion recommended by Kṛṣṇa — sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja — should be given up as irreligion.
To create a new type of dharma has become fashionable in this age. So-called svāmīs and yogīs support that one may follow any type of religious system, according to one’s own choice, because all systems are ultimately the same. In Śrīmad-Bhāgavatam, however, such fashionable ideas are called vidharma because they go against one’s own religious system. The real religious system is described by the Supreme Personality of Godhead: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja. The real religious system is that of surrender to the lotus feet of the Lord. In the Sixth Canto of Śrīmad-Bhāgavatam, in connection with Ajāmila’s deliverance, Yamarāja says, dharmaṁ tu sākṣād bhagavat-praṇītam: real religion is that which is given by the Supreme Personality of Godhead, just as real law is that which is given by the government. No one can manufacture actual law at home, nor can one manufacture actual religion. Elsewhere it is said, sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje: the real religious system is that which leads one to become a devotee of the Supreme Lord. Therefore, anything opposed to this religious system of progressive Kṛṣṇa consciousness is called vidharma, para-dharma, upadharma or chala-dharma. Misinterpretation of Bhagavad-gītā is chala-dharma. When Kṛṣṇa directly says something and some rascal interprets it to mean something different, this is chala-dharma — a religious system of cheating — or śabda-bhit, a jugglery of words. One should be extremely careful to avoid these various types of cheating systems of religion.
Everyone should strictly follow the principles of varṇa and āśrama as given in the śāstra. In the Viṣṇu Purāṇa (3.8.9) it is said:
puruṣeṇa paraḥ pumān
viṣṇur ārādhyate panthā
nānyat tat-toṣa-kāraṇam
One should focus upon the destination for progress, which is to become Kṛṣṇa conscious. This is the aim and end of all varṇas and āśramas. However, if Viṣṇu is not worshiped, the followers of the varṇāśrama institution manufacture some concocted God. Thus it has now become fashionable for any rascal or fool to be elected God, and there are many missionaries who have concocted their own gods, giving up their relationship with the real God. In Bhagavad-gītā it is clearly said that one who worships the demigods has lost his intelligence. Nonetheless we find that even an illiterate person who has lost all intelligence is elected God, and although he has a temple, it has meat-eating sannyāsīs, and many polluted activities go on there. This type of religious system, which misguides its poor followers, is strictly forbidden. Such pretentious religions should be stopped altogether.
The original system is that a brāhmaṇa should actually become a brāhmaṇa; he should not only take birth in a brāhmaṇa family, but must also be qualified. Also, even if one is not born in a brāhmaṇa family but has brahminical qualifications, he must be considered a brāhmaṇa. By strictly following this system, one can be happy without extra endeavor. Sva-bhāva-vihito dharmaḥ kasya neṣṭaḥ praśāntaye. The real aim of life is to mitigate distress, and one can do this very easily by following the principles of śāstra.
