Load of nonsense. This was given by yet another friend who thinks I could benefit, NO! The thing one realises when multiple versions of the books by different authors are given to you is the realisation dawns that there is no standard and therefore it has no meaning. If you believe in this then good for you and I Shall not mock for that is mean.
In conclusion, there is no foundation to this because there are too many variations.
