[quote="Malcolm"][ The situation with the Karmapas is difficult, /quote]
Personally I don't get what is so difficult. As Tulku Urgyen explained it (to me personally in a private conversation when i asked him directly his opinion on the controversy which was in full swing at the time) being a buddha the Karmapa can manifest innumerable tulkus, and not just in this world, universe or realm, so the fact two got recognized is no big deal, as countless ones go unrecognized. Furthermore, both Situ and Sharmar were both devoted students of the Karmapa and would only ever do what they feel is best for him, unfortunately there respective views to this end were at odds.
To this i would add that unfortunately in the political and legal world we live in only one person can take the formal seat at Rumtek and hence assume dominion over all the Karma Kagyu holdings throughout the world which amounts to a lot of real estate and political power. But that is just a corporate position and whether or not one holds such a position does not reflect in anyway on one's spiritual standing. In fact, the lower profile with fewer corporate responsibilities might arguably be preferable from a practice and teaching perspective as one can act free of the constraints of bureaucracy, politics etc.. So personally i feel that all the strife, hate, proclaiming one Karmapa higher than the other, etc. are little more than displays of ignorance and grasping.
