Even though this world is full of resources, you will get only what you are destined for!!! Nothing less, nothing more but only what you deserve!!! This is no joke... It's all karma of an endless cycle of birth and death life after life. 

These material bodies are like machines and the souls are seated in these machines based on their karma. The Lord is rotating the bodies of these souls. So sometimes we come here as man and other times as woman and the cycle goes on for various reasons like femists, anti-feminists etc.
