Heaven, by definition, is basically to exist in a state of complete and total euphoria. To coincide with this definition, one must mentally feel heavenly, and perceive themselves existing in a place of total perfection. Humans interact and experience events through our natural senses and cognitive thought. Therefore, to truthfully be in a heavenly state, one’s senses must entirely perceive one’s environment as heaven. Also, your sentience in general, the state and awareness of your “soul” must believe itself to be existing without flaw or limitation. Honestly, it is difficult to imagine a location or being of heaven without simplifying or limiting the concept.
The real question however, is whether heaven is an identifiable area or if it is simply a state of existence. Well, whether it is a place or not, heaven must exist in a mental and spiritual sense to even fit the definition of the word. If heaven exists, it must in this fashion. Must heaven be an actual place or not? This question is purely speculative. There is no real answer, as there is no serious evidence to point either way. One perspective, though, is that heaven must be both. For heaven to be potentially tangible, in the human sense of the term “heaven”, then it must be a place and a state of mind. Whether you are a Christian, Buddhist, Muslim, Hindu, or even Agnostic, the very definition of the word heaven is to exist mentally and physically in a state of pure euphoria and perfection. A state of mind resembling heaven would be more accurately classified as “enlightenment”, more similar to the ultimate spiritual goal in Buddhism.
In short, Heaven may be a place. However, for heaven to exist at all, it must minimally be a state of mind. A state of awareness and understanding that may or may not extend to perfecting the means through which we interact with the world, creating the possibility of a physical “Heaven.” Heaven could be more simply described as simply the individual outlook of one’s own existence. It is reasonable to believe that a person may obtain a level of happiness or satisfaction in life to be simply content. To have no regrets or to be completely satisfied with one’s own experiences and achievements in a more down to earth sense could be called a state of heavenly existence. A person’s individual perspective and self-valuation of their life determines whether their existence is closer to a “heaven” or a “hell” model. Really, a person’s ability to put themselves mentally into a “heavenly” frame of mind is the only means of manifesting any real heaven. Heaven lies in one’s own mind and heart, and there is no stock, general heaven. It would be conceited to declare that heaven either exists or does not exist. Heaven may exist, but logically, it most likely can not exist generally as a place, without being structured around the heavenly precepts of the individual. Heaven may exist as a physical location, but for it to honestly exist, it must be a synchronisation of human consciousness. Personally, it would be better to keep our individuality.
