Mystic experiences

Till the end of 2005 I had a solid empirical approach to life with my views similar to those expressed by mainstream science. However since then experience has made me wiser. Now its impossible to ignore the experiences I and certain other people have had which cannot be easily understood. I know of more than a dozen people who have experienced inner vibration and effulgence. When concentration becomes profound and interiorized an audible vibration manifests which leads to effulgence when deeply concentrated upon. As the effulgence becomes profound, body consciousness is lost. The point between the two eyebrows and at times certain points at the top of the skull become deeply sensitive to blissful sensations. Many mystical traditions like 'Surat shabad yoga' and Paramahansa Yogananda's 'kriya yoga' elucidate such experiences. However there are major points of disagreement in these mystic traditions. While traditions generally clubbed under 'surat-shabd yoga' and 'santmat' consider ' living Guru' as sine qua non without which the seeker may be waylaid and may even end up in a worse psychological state due to his unguided meditation, SRF/YSS based on the teachings of Paramahansa yogananda who is no longer physicaly alive, stress the need of the right meditation as described in their printed lessons rather than a living Guru.
