Bhagavan Shri Krishna said: O Bharata, these are the various qualities of one who is born with a divine nature (deva) – fearlessness, pure-heartedness, absorption in spiritual knowledge, charity, self-control, sacrifice, study of the Vedas, austerity, sincerity, nonviolence, truthfulness, freedom from anger, renunciation, serenity, aversion to finding faults in others, compassion for all creatures, absence of avarice, gentleness, modesty, steadiness, valor, forgiveness, patience, cleanliness, freedom from envy and the desire for prestige.
Bhagavad Gita - Chapter 16 - Daivasura Sampad Vibhaga Yoga - The Yoga of Discretion
Pride, arrogance, conceit, anger, cruelty and ignorance – these are the qualities manifest in one born of an impious nature (asura).
The qualities of a deva lead one to liberation, while the qualities of an asura cause bondage. Fear not, O Pandava, for you are born of the nature of a deva.
Partha, there are two types of people born into this world – the deva and the asura. I have described devas in detail. Now listen to Me as I describe the asuras.
Those who are asuras by nature cannot discriminate as to what actions should be done and what actions should not be done. No purity, proper behavior or truthfulness can be found in them.
They claim that the world is false, without any basis and without any divinity. They believe that the source of everything is the union between male and female and that life has no purpose besides lust.
With this view, such people with depraved and small intellect flourish and engage in malicious activities for the destruction of the world.
Attached to their insatiable lusty desires and absorbed in pride and arrogance, such people become bewildered and embrace deceitful ideologies, pledging themselves to impure activities.
Believing that slaking their greed and fulfilling their lusty desires is the ultimate goal of life, they undergo unlimited anxieties until the time of death. Bound by hundreds of ambitions and absorbed in lust and anger, they try to amass wealth by any unlawful means in order to satisfy their desires.
They say: “I have gained this today, now I shall fulfill my other desires. This wealth belongs to me and in the future it will increase. This enemy has been slain by me and in the future I will slay others. I am in control! I am the enjoyer! I am perfect! I am powerful! I am happy! I am wealthy and aristocratic. Is there anyone equal to me? I shall perform sacrifices, give in charity and enjoy!” Thus they are deluded by ignorance.
