Hi Prosperity,
I would be interested in the name of your last RM teacher who had the absent to Takata lineage and although my lineage has been verified back to Denise de Tania, there is no further information on her. The Australian Reiki Connection accepts my lineage even with the absent to Takata as all the RM's below Denise de Tania in my lineage have been exceptional practitioners and teachers and their teachings have been demonstrated to be in line with Usui shiki Reiki. I do believe reiki is a personal journey and that one never stops learning or journeying :). There is a wonderful open letter by Carrel Ann Farmer at the www adress reiki.org/CurrentTopics/grmaster.html
which emphasizes this personal journey point well. It is definitely worth a look.
Thanks and reiki blessings,
Ozangel
