BG Chap 16 - The two kinds of people in this world
The two types of people are the divine and the demonic. When a person restricts his inborn attraction and repulsion thru the injunctions of scripture and performs actions according to the scriptures, he is godly. When he gives up scriptural injunctions and acts against them under the control of attraction and repulsion, he is demonic. There does not exist anything other than dharma and adharma in wandering thru millions of births in this universe. Seeing that Arjuna’s lamentation did not dissipate, the Lord elaborates on the qualities of the demons.
