Most ancient/sacred languages like Hebrew and Greek have numerology: each letter represents or is symbolized by a number. Because of this the Bible and Greek mythology can be analyzed with 'gematria' (etc.) and 'isopsephy,' which there must be a similar science of for Sanskrit. Is this true and have there been any numerological studies of the Vedas or other texts? Where could one read a list of Sanskrit numerology or find a classic book on its symbolism?
