I don't think our main life is in the physical. How long have you been alive? How old are you? Now picture eternity. No beginning, no end. Forever. You have existed since before time was created, since before the universe exploded into being. Before there were 6 dimensions, before dimensions were expressed in form. So you see, if you compare the age of the universe (that we know of) and compare it to eternity, it's not long at all. If you compare the concept of time to the concept of unlimited possibility, we haven't really been physical that long, have we? Some people believe that as we experience the dimensional experience that is the universe, most of our being is somewhere else, in something that doesn't exist in terms of physical existence, but has it's being in something different. I don't know if this is true, but it is compelling indeed. If this is true, the rest of the questions don't even apply. Why are you experiencing physicality now? Because you wanted to. "Lowest in the totem pole" has to always be in comparison with something else. There is nothing 'higher' or 'lower' unless there is something else to compare it to. So if everything is one, if there is such a thing as 'potential' and 'eternity', anything that begins or ends has no essential existence, does it? Just food for thought. Thnaks jS
