Bhagavad-gita As It Is
BG Chapters 13 - 18
Taking shelter of insatiable lust and absorbed in the conceit of pride and false prestige, the demoniac, thus illusioned, are always sworn to unclean work, attracted by the impermanent.
The demoniac mentality is described here. The demons have no satiation for their lust. They will go on increasing and increasing their insatiable desires for material enjoyment. Although they are always full of anxieties on account of accepting nonpermanent things, they still continue to engage in such activities out of illusion. They have no knowledge and cannot tell that they are heading the wrong way. Accepting nonpermanent things, such demoniac people create their own God, create their own hymns and chant accordingly. The result is that they become more and more attracted to two things—sex enjoyment and accumulation of material wealth. The word aśuci-vratāḥ, "unclean vows," is very significant in this connection. Such demoniac people are only attracted by wine, women, gambling and meat-eating; those are their aśuci, unclean habits. Induced by pride and false prestige, they create some principles of religion which are not approved by the Vedic injunctions. Although such demoniac people are most abominable in the world, by artificial means the world creates a false honor for them. Although they are gliding toward hell, they consider themselves very much advanced.
Self-complacent and always impudent, deluded by wealth and false prestige, they sometimes proudly perform sacrifices in name only, without following any rules or regulations.
Thinking themselves all in all, not caring for any authority or scripture, the demoniac sometimes perform so-called religious or sacrificial rites. And since they do not believe in authority, they are very impudent. This is due to illusion caused by accumulating some wealth and false prestige. Sometimes such demons take up the role of preacher, mislead the people, and become known as religious reformers or as incarnations of God. They make a show of performing sacrifices, or they worship the demigods, or manufacture their own God. Common men advertise them as God and worship them, and by the foolish they are considered advanced in the principles of religion, or in the principles of spiritual knowledge. They take the dress of the renounced order of life and engage in all nonsense in that dress. Actually there are so many restrictions for one who has renounced this world. The demons, however, do not care for such restrictions. They think that whatever path one can create is one's own path; there is no such thing as a standard path one has to follow. The word avidhi-pūrvakam, meaning a disregard for the rules and regulations, is especially stressed here. These things are always due to ignorance and illusion.
Bewildered by false ego, strength, pride, lust and anger, the demons become envious of the Supreme Personality of Godhead, who is situated in their own bodies and in the bodies of others, and blaspheme against the real religion.
A demoniac person, being always against God's supremacy, does not like to believe in the scriptures. He is envious of both the scriptures and the existence of the Supreme Personality of Godhead. This is caused by his so-called prestige and his accumulation of wealth and strength. He does not know that the present life is a preparation for the next life. Not knowing this, he is actually envious of his own self, as well as of others. He commits violence on other bodies and on his own. He does not care for the supreme control of the Personality of Godhead, because he has no knowledge. Being envious of the scriptures and the Supreme Personality of Godhead, he puts forward false arguments against the existence of God and denies the scriptural authority. He thinks himself independent and powerful in every action. He thinks that since no one can equal him in strength, power or wealth, he can act in any way and no one can stop him. If he has an enemy who might check the advancement of his sensual activities, he makes plans to cut him down by his own power.
