Alright...first of all there is no fixed order of reincarnation. It all depends upon your karma. Im a brahmin( by cast) in this birth but its not important that ill achieve "moksha" i.e. salvation after i die. If i do more wrong deeds than right ill have to come back to pay the price. As they say" you shall reap what you sow". There is no fixed formula or order to this. Why was i born in India and not USA???...i dont know. But i have a strong inclination towards that place. I might have been an american in some birth. Karma i.e. our deeds decide our order of reincarnation and nothing else does. I think through meditation we can connect with our superconcious and try to find the answers to all the" whys?" In our life. And from there on decide the course of our actions. In order to break this cycle of life and death we need to find these answers. If i do wrong deeds like kill people or steal from someone do you think ill attain salvation??? No matter what the chart says...no i wont. Ill have to come back to face the music of my actions...ill go backwards if we talk about the chart. So my friend, our actions our karma decides the order and nothing else...
