What is the soul and how may I approach it?

[jafar]

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?
  

Yes.. exactly...
If the 'over self' never experienced the STS path, it cannot offer any advice to the STSes.

One cannot wrote the 'ultimate guide / walkthrough of Star Wars video game' unless the author has experienced the game and took a Sith avatar walking the path of the Sith.

And among the key things to 'learn', in gradual manner, of those who took the STOs path is how much *they are willing to admit, accept, understand and consider STSes as among their own self.

It's easy to love the 'lovable' while it's not so easy to love the 'unlovable'.

*I uses 'they' (3rd person) reference so I can maintain a neutral posture / view between the 'dance' of STOs and STSes.
