What is the reason to want to be part of an social memory complex?

[jafar]

Maybe upon discovering that 'hiding thoughts and experiences from others' is actually an illusion?
Or upon discovering that there are 'others' who can easily access his/her thoughts and experiences?

It seems to me in one way or another, it boils down to acceptance.
A key feature of acceptance might be forgiving ourselves, and this is the hardest thing.

There is very little guidance in this world on processing catalyst. We are fortunate to have the Ra material.

The above is actually the core message of L01, Jesus, Mohammed, Yogis, Lao Tse and other STOs gurus.

The word "islam" initially means "peaceful acceptance" and then twisted to become a label for a Religion.
Jesus recommends a prayer which contains:
"Let your will be done (#acceptance), Forgive us as we've forgiven others (#forgiveness)". 
And then twisted to become a religion as well.
L01 describe: "This is the game: to know, to accept, to forgive, to balance, and to open the self in love"

When you can easily forgive others you will be easily forgive your own self.
Since 'others' are your own self in the first place, separation is an illusion.

Yet the 'illusion' need to be created in order to have something to be 'accepted' and 'forgiven'. 
Otherwise there will be nothing to forgive or accept.
