This Symbala and the 'Dream Guides' Symbala appeared in a book by William Rainen, published exclusively in Japan.
It was intended to explore the energies of what William called 'the fifth brain wave'. I find its frequencies to be very activating, so that became the name. We have many ways in our techno-age to stimulate our brains, but this way is expanding, yet balancing; stimulating, not jangling. Do you feel the outward rush and the gentle screening of the inflow? I trust you may find it so and a useful tool in your exploratiions.
