I continuously change my past!
Don't you ever find past selfs in disguise who you can talk to and give instructions on what you've understood? don't you ever talk to the little girl/boy you were?
It is very evident that the future determines the present, more than the contrary. Who gave you that beautiful idea to hang around CZ the first time? one can say angels, intelligences of any kind etc. but they would never intervene if you didn't yourself express that intention, because the general rule is not enter uninvited. The past is continuously changed by your intention now, as well as permanently frozen by your eventual sense of guilt now. Time is not linear, it is an illusion and you can play with it, there is nothing inesorable in it, as there are no closed doors in the universe. Have you ever experience a reality shift? our life is loaded with them. That is your past being rewritten.
(so Lapis if you direct some of your programming towards your past, you'll see what a rollercoaster! it is great fun, it is the most powerful tool we have)
