Heaven and hell are states of the mind. They are not actual places or locations. To some people, life on earth seems like hell but to others, life is most beautiful and almost like living in heaven.

Kuthumi (channeled by Lynette Clarke):

For if you ask if there is a place called Hell, the answer is No. If you ask if you can create Hell, the answer is Yes - you can. Hell, as many of you think of it, has been created by man as a form of control through fear. Many have been taught that if you do certain things, you will go to Hell. Also, if you don't follow what you are told, you will go to Hell. Some religions have taught a form of this concept.
