I don't know if this helps you and it would be nice if Andreas would speak to this...if he can...but this is what I have recently started to do to access my higher self...
I've recently purchased the insight and focus CD's offered from www.mercola.com and I listen to the insight CD's twice daily... once in the morning and before going to bed...as I listen I say affirmations out loud and ask my higher self for guidance in many different areas...
You might go to Affirmations forum and see what others are saying about this technique and the use of these types of CD's.
I hope Andreas has something to say about this also... As I too wish to access my higher self (authentic self to its full expression)
