Does you book also reference Blavatsky's Secret Doctrine, Vol 3 called the Synthesis of Science, Religion? At http://books.google.com: search for "Secret Doctrine vayu apas" She has a table of Page 501 showing how it all corresponds. Perhaps you could snap the page and post it separately because it can't be done as a comment. In fact, she states there are seven Tattwas, not five. This matches how Sri Aurobindo described it to Pavitra. http://www.mirroroftomorrow.org/blog/_archives/2009/1/2/4042583.html Sri Aurobindo: The ancient seers told that everything was going by seven. But in the present state of evolution there are in play only five principles of which perception is possible. But very likely, there are seven Tattwas.
