In our life, we always compare with some one else and live life.Many times the comparision make us to live life in a sickness.For E.g- if some one is earning more than us we just compare him/her with our earnings and that makes one to go mentally sick!!.If, this comparision make us to grow or motivate one to the higer task it is good.In general, in the schools the students used compare oneself with others by their marks.When it comes to life standards , it is many time put people in utter comparision...We also need to remember we are the one ,who set our reality.

What OSHO says about comparision is here for your view:-

"Jealousy means to live in comparison."

Somebody is higher than you, somebody is lower than you. You are always somewhere on a middle rung of the ladder. Perhaps the ladder is a circle because nobody finds the end of the ladder. Everybody is stuck somewhere in the middle, everybody is in the middle. The ladder seems to be a round wheel.

Somebody is above you – that hurts. That keeps you fighting, struggling, moving by any means possible, because if you succeed nobody cares whether you have succeeded rightly or wrongly. Success proves you are right; failure proves that you are wrong. All that matters is success, so any means will do. The end proves the means right. So you need not bother about means – and nobody does bother. The whole question is how to climb on up the ladder. But you never come to the end of it. And whosoever is above you is creating jealousy in you, that he has succeeded and you have failed.

OSHO
