kiyān vārthaḥ sva-para-druhā dharmeṇa
sva-drohāt tava kopaḥ
para-sampīḍayā ca tathādharmaḥ
Any religious system but the process of bhāgavata-dharma — service as an eternal servant of the Supreme Personality of Godhead — is a system of envy of one’s own self and of others. For example, there are many systems of religion in which animal sacrifices are recommended. Such animal sacrifices are inauspicious both for the performer and for the animal. Although one is sometimes permitted to sacrifice an animal before the goddess Kālī and eat it instead of purchasing meat from a slaughterhouse, permission to eat meat after a sacrifice in the presence of the goddess Kālī is not the order of the Supreme Personality of Godhead. It is simply a concession for the miserable person who will not give up eating meat. It is meant to restrict his desire for unrestricted meat-eating. Such a religious system is condemned. Therefore Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja: “Give up all other duties and surrender unto Me.” That is the last word in religion.
One may argue that the sacrifice of animals is recommended in the Vedas. This recommendation, however, is a restriction. Without Vedic restrictions on the purchase of meat, people will purchase meat from the market, which will be overflooded with meat shops, and slaughterhouses will increase. To restrict this, sometimes the Vedas say that one may eat meat after sacrificing an insignificant animal like a goat before the goddess Kālī. In any case, a system of religion in which animal sacrifices are recommended is inauspicious for those who perform the sacrifices and for the animals. Envious persons who perform ostentatious animal sacrifices are condemned in Bhagavad-gītā (16.17) as follows:
yajante nāma-yajñais te
“Self-complacent and always impudent, deluded by wealth and false prestige, they sometimes perform sacrifices in name only without following any rules or regulations.” Sometimes animal sacrifices are performed very gorgeously with grand arrangements for worshiping the goddess Kālī, but such festivals, although performed in the name of yajña, are not actually yajña, for yajña means to satisfy the Supreme Personality of Godhead. Therefore it is recommended that in this age specifically, yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ: those who have good intelligence satisfy the yajña-puruṣa, Viṣṇu, by chanting the Hare Kṛṣṇa mantra. Envious persons, however, are condemned by the Supreme Personality of Godhead as follows:
ahaṅkāraṁ balaṁ darpaṁ
kāmaṁ krodhaṁ ca saṁśritāḥ
tān ahaṁ dviṣataḥ krūrān
kṣipāmy ajasram aśubhān
āsurīṣv eva yoniṣu
“Bewildered by false ego, strength, pride, lust and anger, the demon becomes envious of the Supreme Personality of Godhead, who is situated in his own body and in the bodies of others, and blasphemes against the real religion. Those who are envious and mischievous, who are the lowest among men, are cast by Me into the ocean of material existence, into various demoniac species of life.” (Bg. 16.18-19) These persons are condemned by the Supreme Personality of Godhead, as indicated by the words tava kopaḥ. A person who commits murder is envious of himself and also the person he has killed, for the result of committing murder is that he will be arrested and hanged. If one transgresses the laws of a man-made government, he may escape being killed by the state, but one cannot escape the laws of God. A killer of any animal must be killed in his next life by the same animal. This is the law of nature. One must follow the instructions of the Supreme Lord: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja. If one follows any other system of religion, he is subject to punishment by the Supreme Personality of Godhead in many different ways. Therefore if one follows a concocted system of religion, he is envious not only of others but also of himself. Consequently his system of religion is useless.
Śrīmad-Bhāgavatam (1.2.8) says:
dharmaḥ svanuṣṭhitaḥ puṁsāṁ
notpādayed yadi ratiṁ
śrama eva hi kevalam
“Duties (dharma) executed by men, regardless of occupation, are only so much useless labor if they do not provoke attraction for the message of the Supreme Lord.” Following a system of religion that does not awaken one’s Kṛṣṇa consciousness, or God consciousness, is merely a waste of time and labor.
