Hankaar, Hankār or Ahankar, is the Gurmukhi word originated from a Sanskrit word Ahankāra (Hindi or Sanskrit: अहंकार) which translates to mean ego or excessive pride due to one's possessions, material wealth, spirituality, beauty, talents, physical strength, intelligence, authoritative powers, charity work etc. It gives an individual the feeling that he is superior to others and therefore they are at a lower level than he is. It leads to envy, feelings of enmity, and restlessness amongst people. It occurs in a person only when the person is in देह बुद्धि i.e. when he consider himself a 'body' only (as a soul, we possess body). So, ahemkaar is a product of अस्मिता loss of true identity.
