Master Subramuniya seemsto have been a Western yogi, who was associated with the Himalayan Academy in the second half of the 1900’s, and that he had founded the Saiva Siddhanta Church in Kaua, Hawaii. He is no more among the living.
In my early twenties I found a little book written by him, called The Clear White Light. In this booklet he explains the process of meditation and the manifestation of the inner light (what generally is called ‘enlightenment’). Maybe because he was a Westerner, his explanation is, for us Westerners, simple, clear and understandable. The booklet also contains a glossary for terms, some of which the author seems to have made up to express certain concepts.
I find his booklet very enlightening. If you are interested in the process of enlightenment, you can read the booklet here: The Clear White Light.
