A PROFESSIONALLY RECORDED MASTER KEY SYSTEM AUDIO BOOK

Music for your mind

There are a number of Master Key System audio books on the market. Some commercial, others free of charge. Yet there's nothing like the new Mr. Master Key audio book.  Recorded by a professional voice artist who also studies the Master Key System (!), enhanced with custom-composed music by a professional producer, and mixed and mastered by Helmar Rudolph. 
More than 11 hours of playing time - a masterpiece for only 79.00 Euro
This audio book includes the extended foreword from the 1941 UK Edition as well as Helmar's extensive commentary, which was carefully woven into the original.
ALMOST INEVITABLE

You never walk alone

Since tens of thousands of people from all over the world have purchased Helmar's products and services. The vast majority of them from German-speaking countries, and others from the USA, Canada, Sweden, the Netherlands, Japan, the UAE - to name but a few.  Below two references from very happy campers.
I have been actively seeking for the past three years, and as soon as I saw your Kybalion videos I realized this was the next step - that this was the culmination of everything. I am so stoked. Thank you so much for all of your work!
