Tazkiya-e-Nafs or Purification of the ego...Purification of the carnal self, in a word or two involves freeing oneself from its attributes. A beginner on the path to Allah Ta'ala can purify his ego by rejecting the inclination toward evil and by taking his carnal self to the task of accounting for its slips and short-comings. At the intermediate stage, purification involves guarding oneself against the undesirable qualities of:--
(a) Jealousy (b) Avarice (c) Malice (d) Not bearing grudges nor causing anyone harm and (e) Not telling lies nor deceiving anyone.
To the adept, Purification involves focussing all of one's attention on one's relationship with Allah Ta'ala.
