(One man follows the divine path and another man follows the demoniac path—description below*)
The following verses from the Bhagavad-gita provide an overview of the 16th chapter entitled, "The Divine and Demoniac Natures." For a more complete understanding, please refer to the Bhagavad-gita As It Is with elaborate purports by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada.
The Blessed Lord said: Fearlessness, purification of one's existence, cultivation of spiritual knowledge, charity, self-control, performance of sacrifice, study of the Vedas, austerity and simplicity; nonviolence, truthfulness, freedom from anger; renunciation, tranquility, aversion to faultfinding, compassion and freedom from covetousness; gentleness, modesty and steady determination; vigor, forgiveness, fortitude, cleanliness, freedom from envy and the passion for honor—these transcendental qualities, O son of Bharata, belong to godly men endowed with divine nature.
Arrogance, pride, anger, conceit, harshness and ignorance— these qualities belong to those of demonic nature, O son of Pṛthā.
The transcendental qualities are conducive to liberation, whereas the demonic qualities make for bondage. Do not worry, O son of Pāṇḍu, for you are born with the divine qualities.
O son of Pṛthā, in this world there are two kinds of created beings. One is called the divine and the other demonic. I have already explained to you at length the divine qualities. Now hear from Me of the demoniac.
Those who are demoniac do not know what is to be done and what is not to be done. Neither cleanliness nor proper behavior nor truth is found in them.
They say that this world is unreal, that there is no foundation and that there is no God in control. It is produced of sex desire, and has no cause other than lust.
Following such conclusions, the demoniac, who are lost to themselves and who have no intelligence, engage in unbeneficial, horrible works meant to destroy the world.
The demoniac, taking shelter of insatiable lust, pride and false prestige, and being thus illusioned, are always sworn to unclean work, attracted by the impermanent.
They believe that to gratify the senses unto the end of life is the prime necessity of human civilization. Thus there is no end to their anxiety. Being bound by hundreds and thousands of desires, by lust and anger, they secure money by illegal means for sense gratification.
The demoniac person thinks: "So much wealth do I have today, and I will gain more according to my schemes. So much is mine now, and it will increase in the future, more and more. He is my enemy, and I have killed him; and my other enemy will also be killed. I am the lord of everything, I am the enjoyer, I am perfect, powerful and happy. I am the richest man, surrounded by aristocratic relatives. There is none so powerful and happy as I am. I shall perform sacrifices, I shall give some charity, and thus I shall rejoice." In this way, such persons are deluded by ignorance.
Thus perplexed by various anxieties and bound by a network of illusions, one becomes too strongly attached to sense enjoyment and falls down into hell.
Self-complacent and always impudent, deluded by wealth and false prestige, they sometimes perform sacrifices in name only without following any rules or regulations.
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.
Attaining repeated birth amongst the species of demoniac life, such persons can never approach Me. Gradually they sink down to the most abominable type of existence.
There are three gates leading to this hell—lust, anger, and greed. Every sane man should give these up, for they lead to the degradation of the soul.
The man who has escaped these three gates of hell, O son of Kuntī, performs acts conducive to self-realization and thus gradually attains the supreme destination.
But he who discards scriptural injunctions and acts according to his own whims attains neither perfection, nor happiness, nor the supreme destination.
(Bhagavad-gītā As It Is 16.1-23, Translations)
*Two men (standing where the stairway makes its turn) are being offered both liberation and bondage. One man looks upward, following the spiritual master who points toward Radha-Krishna in the spiritual world. The other man embraces the demoniac qualities by accepting the garland offered by maya, Krishna's illusory energy. Drawn by ropes which are held by the personifications of lust, greed, and anger, he follows her down the steps. At the bottom he is reaching for maya, and gliding towards hell.
