A very good article just crossed my way

(unfortunately it is only available in german language, Kristalline Energiearbeit - Loesung ohne Drama, by Andreas Giesen (PDF))

Andreas points out the core of our essence in a scientific-mystical way without the heavy burden that both directions can inherent at times.

He uses the term "crystalline realm" to describe the basic core of our perceived existence. Over time our experience has formed programs that determine our daily reactions, thoughts, emotions and thus again experiences. The control panel that activates these programs is the crystalline realm itself. According to the author any negative feelings have their origin their and basically derive from the assumption that we are separated from the world around us.

The good news is that we can access these realms by breathing deeply and expanding our consciousness and either set goals that lead us towards dissolution of the negative feeling or thought pattern. Or alternatively we can go to the core of that pattern and transform it that way. Both ways are powerful, and as Andreas says, are beyond affirmations because they lead us back to our essence.

Really worth reading, if there should be an English version available, I'll post it as soon as possible.
