Paul and Gavco --

a bit of a lag between the above and this; but fyi, the biography in question (written originally by Bhau Kalchuri in Hindi, then translated into English -- the 20 volumes you mention) is entitled LORD MEHER (in English -- or MEHER PRABHU in the original). The entire text (all 6,742 pages of it) is available online! -- see:

www.lordmeher.org/index.jsp

Regrettably, the online edition is not, so far, replete (as is the printed edition) with photographs (a notable feature of a notable work). But there's a lot of reading one can do there. And a search feature also can be used for research of various sorts.
