What always troubles a worker or for that any man is his egoistic tendency. It need to be taken care of in a special way. Else, the egoistic feelings grow by leaps and bounds and this is not desirable in any case. Mananeeya Eknathji says :
"I have done this", or "This was done because of me" or "This continues because I am striving for it." Such a feeling grows and it is harmful for the full growth of the individual. As a matter of fact here instead of the gross interest of the body-mind, it has been shifted to the subtle interest of the ego. The body-mind complex is eliminated. But again, the betterment is a relative idea. What may be good and beneficial according to me, may not be so according to another and what is good today may cease to be good tomorrow. In this world good and evil go together. They are just the obverse and the reverse sides of the same coin of life. What appears to be pleasure today results in pain tomorrow, that is the law of life.
Yattadagremrutopamam Pariname Vishamiv.. Bhagavadgita XVIII.38 That happiness from the contact of the sense organ with its object, which in the beginning is like nectar and when it changes is like poison is actually the position of ego.
Surrender, constant surrender is the only way out. The more we surrender ourselves, the more we would be in a position to conquer ego.
