People are born in a state of sitra, a state of not having sin. We deny original sin. What are some other conditions necessary for forgiveness of sins. Sincerely repent of your sins. Heaven is the same as Paradise.
People have eternal happiness there.
Heaven is a place of pleasure. There are women there. There is sexual activity between the men and women. You can have sex with more than one woman, not a system of marriage, but they will be husband and wife. In each room is a woman with whom you can have sex with, but no pregnancy.
