No, I don't believe it exits.
I was thought by my parents that if you do good, it will always return to you one day. But seeing the current scenario where people fight over each other for a place, fame, position etc and when you see children and women in some part of the world suffer for no bad they have done, its hard to believe Karma exists. I feel the whole concept of karma has faded in todays competitive world and would like to see a different take on it. It always good to know that 'Karma' exists!!
These are some questions we should look at, refrering to Buddhism.
What is the cause of the inequality that exists among mankind?
Why should one person be brought up in the lap of luxury, endowed with fine mental, moral and physical qualities, and another in absolute poverty, steeped in misery?
Why should one person be a mental prodigy, and another an idiot?
Why should one person be born with saintly characteristics and another with criminal tendencies?
Why should some be linguistic, artistic, mathematically inclined, or musical from the very cradle?
Why should others be congenitally blind, deaf, or deformed?|
Why should some be blessed, and others cursed from their births?
