Frustration is no good. So I will continue in my attempt in confusing you. Before you get annoyed at that have a look at page 125 of the PhotoReading book and see what frustration is doing to you. And why I want to move you to the direction of confusion.
In what way is a "grounding in vitamins and minerals" a broad or narrow overview of the subject? HOW will you know WHEN you have a grounding?
You keep asking me why it isn't a purpose. My simple answer is, because it's not getting you anywhere. If it was a purpose you'd know exactly WHEN you got what you were asking for.
If you want to insist that it is a purpose you tell me how you measure your grounding?
