WHY Human Born on Earth

First of all ,All people in this world want to know that why the life is exist on this planet,However this is the most difficult questions to answer,But sikhism give the infromation regarding this in a very good way . when we believe that i can do good things and bad things we create a self illusion about that some thing is done by us, This is the opposite side of the will of god whenever we believe in sin or pap or pun we have to born again because we dont have the proper knowledge about us that we can not do anything, this thing that we written inside or heart that is different than gods will so to remove this illusion we have to born again...This is just a cause or our birth....some body is writing inside their heart of balance of paap and punn sin ,,,this thing is a reason of that we are against the will of god, When we understand that what is will of god we leave our thinking that i can do this or i can do that ,we totally disconnected from brain and we use only brain to understand the gurbani ,,,because we already know that by my thinking nothing is happening and my thinking is wasted of time and this thinking is taking me far away from the gods will. Our thing and gods thinking collide with each other but our thinking so so weak and gods will so powerful so in the end gods will win but when we think that creates a illusion and we fell into the darkness. god gave us the body to remove this darkness to understanding the gods will ,,by understanding gurbani we can undersatnd the gods will.This thinking creates sorrow and pain in our life some times when we think that why these things happening to me we forget that these things are created by me my bad thinking created these pain in my heart.so gurbani warn us to not thinking against the will of god.
