The question here is, any other Lama could have given this talk and teach these students Buddhism, but why is it that the Dalai Lama has to do it personally? Couldnt another Lama or another professor take over the Dalai Lama's role in educating these young people? Or is it that they lack people so much that the Dalai Lama himself has to step up and take up this job? Sure, it is a great blessing to the students on the surface, but if you think deeper, it just shows the lack of a sense of responsibility that the CTA has. If they are doing a great job at this department, they wouldnt need the Dalai Lama to do this personally.
