Bhagavad Gita 16.18अहङ्कारं बलं दर्पं कामं क्रोधं च संश्रिताः।मामात्मपरदेहेषु प्रद्विषन्तोऽभ्यसूयकाः ॥

They are selfsufficient and puffed up with mental and material power. They pose too much. They resent it much if they are belittled. The body is dearer to them than everything else. They live solely for it. If anybody tries to thwart their plans or schemes they become bitterly hostile towards him. They take vengeance on him and try to kill him mercilessly. They are extremely meanminded. Just as darness seems to be denser after night sets in, so also as their,folly increases, their arrogance grows, their egoism develops, their pride swells, and their delusion augments day by day. They use brutal force to gain their selfish ends. They abuse and illtreat all those people who are truthful and charitable, and who are devoted to Me.Ahamkaram Egoism The selfarrogating principle, the effect or modification of ignorance. This is the source of all the defects and perversities in human nature and of all evil actions. Lust, anger, greed, pride and hypocrisy are all attendants of egoism. It is very difficult to overcome this dire enemy, but through Vichara (right enquiry) it can be annihilated.These Asuras who are very egoistic on account of their deep ignorance esteem themselves very highly for the alities they possess and for those which they falsely superimpose upon themselves
