Comparison of meditation approaches - Gill Edwards

[Neo]

I blew some dust off an old book in my library, and it was Gill Edwards - Stepping into the Magic - never finished reading it.

How do you find Gill's approach of mentally imagining / day dreaming of meeting what she calls your Basic self and Higher Self?

 

Much like what you would find in a  hypnosis session, you take steps down into a forest to meet your basic Self, or to meet your higher self, up to a glass temple / tower (where nobody is home)

and optimistically states you may find who is in the glass temple on the first attempt!

How do these different approaches fair?
