PROBLEM OF EGOISM

Question: How to get rid of Egoism (ahankaar) and a "Sense of Mine" (mamtaa)?

From the standpoint of the Discipline of Disinterested Action:
(Karmayog)”'Nothing is mine; because I have no independent claim on things,
persons, circumstances, incidents and situations etc. When nothing is mine, it
means that I need nothing, because if the body is mine, then food, water and
clothes etc. for the body become my necessity; but if the body does not belong
to me at all, then I have no requirement of anything for myself. When there is
clear understanding that nothing is mine and I need nothing, there is no
question of egoism (feeling of I), because egoism "I-ness" persists by accepting
affinity for the body, things and circumstances etc.
The fact is that the so-called body of mine has an affinity for the world, so it
should be used to render service to the world, because I for myself needs
nothing. By having this sort of feeling, egoism perishes and a spiritual
aspirant becomes free from egoism and a sense of mine.
From the standpoint of Discipline of Knowledge (Jnanayog):” Every man has the
inherent realization and knowledge that 'I am'. In I am', 'I', is a part of
nature and 'am' denotes 'reality' (Eternal Existence). This 'am' is used with
'I' ”In the absence of 'I', 'am' will not stand. only 'Is' will remain.'
'I am', 'you are', 'this is' and 'that is' all these four, are in respect of
individuals, space and time. This is limited conception. If this limited
conception of individual, distance and time is not held on to, then universal
'Is' remains. When a aspirant is established in this universal 'Is', he becomes
completely free from the sense of 'I' and 'mine'.
From the standpoint of Discipline of Devotion (Bhaktiyog) - What is called 'I'
or 'mine' actually belongs to God, because had the persons, things, body been
mine, I might have protected them from decay and had rights over it (possessed
it) forever. But it is not so. It means that the so-called body of mine, senses,
mind, intellect etc., are His and I am also His. By having this sort of feeling,
a striver becomes free from the sense of mine and egoism.
