In the last few decades, many of the Earth's most profound wisdom and healing traditions have come to be openly shared. Often they were closely guarded secrets until recent years. The Internet now makes such information, and the teachers to learn it from, easy to find.
Techniques for healing with sound are among the oldest in the world. Yet even a generation ago, such knowledge was either disregarded by the mainstream, hidden by traditional healers, or both.
I consider the wide availability of such knowledge---and the traditional tools and methods for applying it---to be a very great blessing indeed.
How about you?
