Saraswatidevi

Namaskars Prabhu. I would like togreet everybody on this forum... I am a jyotish enthusiast, very green and fresh in the field ;-) live in Mlecchaland on the top of this ;-P. Presently, I am studying the influence of Atmakaraka Graha but I stumbled on a question a bit too much... Since Ketu cannot be a Atmakaraka,I amin a great doubt now as I study a chart of a native with the following birth data: male P., born on 10 of Jan,1976; loc.time: 13:15; time zone:+1 E of G, no DST, Lat.:45 N 48 20 and Lon.: 8 E 50 30, and computer data says his Vimshottari is Ke/Ra (25deg 14min in Ari/Lib rashi), which are most exalted in degrees, the Surya following closely (25deg 51min Cap)... I am confused whether Rahu or Surya are his Atmakaraka... Can somebody 8prefferably a senior member) point out to me a method how to eliminate Rahu as Atmakaraka, since I am too ignorant to figure out? I would be in a tremendous debt to you... With regards, Jaya Radhe
