Given how relevant the number: how much you think of yourself, this soul correction is to take yourself out of the picture, completely. Stand outside and know that nothing is about you.
And as long as you think it is, you'll have misery, you'll not breathe deeply, you'll feel hurt, or important, or whatever self-centered things you fancy yourself.
The issue with the soul correction is trust. The lack of it. No trust in other people, no trust in the Universe. Closed in, relying only on one's own experience. Nothing is accepted at face value.
This is the soul correction of the Tree of Life... the skeptic will test everything.
The problem is that one can't experience everything in a "normal" life, and therefore most decisions come as a reaction from an ego truth... and they are wrong decisions.
There is a much bigger world with a lot bigger view than a typical Forget Thyself person can see. So a Forget Thyself is mostly a bumbling idiot, making mistake after mistake.
Trust is hard, because trust is something you give, like love, no one can give you trust. Trust is like putting wood in the fireplace even though you don't know it will every give you heat...
A typical Forget Thyself has two aspects: they look self-assured, confident, maybe even arrogant to others. The inner aspect is miserable, tormented with doubt, self-hate, grief, regret. Not a pretty picture. No bridge between the two worlds, without altering both: softening the harsh certainties outwards, and softening the lack of trust inward.
An evolved Forget Thyself has developed the capacity of small steps, feeling their way, listening keenly, moving like one moves in pitch dark places, paying attention and awareness to every shift in vibration, in temperature, sound...
Awareness is the other side of Forget Thyself's distrust.
A very difficult and involved soul correction.
Moses had this soul correction.
Your best bet to do this is under guidance by another Forget Thyself person (me). https://www.yourvibration.com/path
