@macusantoniu, the Dalai Lama is reaching out to other Buddhist tradition and asking them all to engage in the world's problems ogether using what Buddha taught to bring peace and harmony.

Harmony among the Different Buddhist Traditions

Now, as I mentioned yesterday when we met the leaders from Burma and Laos and some others, in the past, because of the names so-called “Hinayana,” “Mahayana” and “Tantrayana,” people got the impression these three yanas [vehicles] are something really different and separate. That’s totally mistaken. As I mentioned briefly this morning, the Theravada tradition, or Pali tradition, is the foundation of Buddhadharma; and the practice of vinaya [monastic vows and discipline] is the foundation of Buddhadharma.
