What is the soul and how may I approach it?

[Sacred Fool]

What intrigues me most is an 'over self' could have a mixed of 'self' who took STS and STO path, the path of unity and path of separation.
Similar to playing Star War video games and having an avatar who took the Jedi path, and another avatar who took the Sith path. Just to experience how the game flow on both path.

  
If an Higher Self were to have no understanding of the STS path, then it could not advise and assist its incarnational off-springs which travel into STS realms.  One could etiolate--to use a Ra word--this argument to suggest that, therefore, we all have had, or will have, such experiences in other incarnations.  This kind of sounds like Oneness, doesn't it?
