Does Haven Exist and what one need to do to go to haven?

There are different different definition for haven in different religion , in some religion food is good , in some case there are floating lady out there waiting for you , but one question we need to ask our self that what we will do with all these things,  if we do not have body . Let me tell you one funny incedence ,One day a Guru ask to students, what we should for heaven , one very intelligent boy told we need to help needy people , boy person told we need to share our income with poor people ,but in back bench one student was sitting there he told you will have to die for heaven,every one was laughing . So moral is no one know truth you need to find truth , and if some one is claiming that he know haven he cheating you, you most understand this very fundamental thing .As per Hindu scriptures, it is mentioned that lord Yamraja comes  . Probably few workmen with Yamraj come , suck the life out of a person and take him to hell. Jesus exhorts believers to pray, “God's will be done in Earth as it is in Heaven.” He also told many parables about the Kingdom of Heaven, and He said it is where God's throne is. But still an actual description of Heaven has never been given. So according to Christianity heaven is a endless place in universe , but have not any clear picture of it. According to Krishan said you will experience the comfort of heaven and atrocities of hell both on this earth before death .
Dhritrashtr asks : “I was a good king to my subjects, a good husband and a good father. Then why did I suffer the most in this war (he lost his 100 sons)” ?To this Lord Krishna reminded him of an incident from 50 lifes ago where he destroyed a bird’d nest and told him that it was karmic balance that happened in this birth of his. (Comment if you want to know the whole story).When a human lives on the Mrityuloka (Earth), his materialistic mortal body suffers happiness and pains. But after the death of human, the soul suffers pain or happiness in the hell or heaven on the basis of good deeds and bad deeds of that human being on Earth .
If you read all these you will get confuse , you will never know the truth. Best way to come to right conclusin is just try to understand life in your way . Because you will never know truth , and if some one knows he can not explain to you because he is not alive. I am not against any scriptures .
