A part of me wants to believe that our soul consciousness has set up this life cycle in advance to present a set of circumstances that will give us opportunities to choose a master path... or not.
To face challenges and make decisions based upon the best moral aptitude and spiritual enhancement that can be obtained. Therefore the path is unique to each of us.
There is never a right or wrong way, really. Only the illusion of judgement about something.
Somewhere out of this "soup" our true identity, our authentic self might emerge.
We've only got maybe 70 or 80 years to sort it out.
For some, that's more than enough while others may need many lifetimes to get every aspect of this existence.
Or, more likely, infinite aspects require as many lifetimes.
And if we are indeed all connected, then we must surely feel on some level the other 7 billion souls incarnated as well. How many examples can there be?
