On "Understanding" the Law of One

[third-density-being]

What I don't understand is why can't or shouldn't I understand ? It makes it really hard to take anything from any of the Material sometimes.

As I uderstood it, it is not necessary to have this Wisdom to be Harvested of this density. Teachings Ra offered was only for Those whom were/are looking for this Wisdom. Some it may allow to reach Their goals in this incarnation.
I begin to understand that "knowledge" is only an instrument to properly integrate all that comes from your "I". Its those feelings and your attitudes towards your Self/Other-Selves/Creation that express your polarization (when chosen of course) - Choice is this density work - not understanding.
That's why One doesn't need to "know" to do the "work".
