The sixteenth chapter of the Bhagavad Gita is Daivasura Sampad Vibhaga Yoga. In this chapter, Krishna describes explicitly the two kinds of natures among human beings - divine and demoniac. Those who possess demonaic qualities associate themselves with the modes of passion and ignorance do not follow the regulations of the scriptures and embrace materialistic views. These people attain lower births and further material bondage. But people who possess divine qualities, follow the instructions of the scriptures, associate themselves with the mode of goodness and purify the mind through spiritual practices. This leads to the enhancement of divine qualities and they eventually attain spiritual realization.
Being born among the demoniacal species in births after births, the foods, without ever reaching Me, O son of Kunti, attain conditions lower than that.OPEN VERSE
This door of hell, which is the destroyer of the soul, is of three kinds-passion, anger and also greed. Therefore, one should forsake these three.OPEN VERSE
O son of Kunti, a person who is free from these three doors to darkness strives for the good of the soul. Then, he attains the highest Goal.OPEN VERSE
Ignoring the precept of the scriptures, he who acts under the impulsion of passion, -he does not attain perfection, nor happiness, nor the supreme Goal.OPEN VERSE
Therefore, the scripture is your authority as regards the determination of what is to be done and what is not to be done. After understanding (your) duty as presented by scriptural injunction, you ought to perform (your duty) here.OPEN VERSE
