These recordings are from Brussels, September 1979. That year Rinpoche taught the Buddha Nature by the Regent Maitreya very extensively, spanning 90 talks, to the students who were interested in becoming translators or studying texts directly in Tibetan.
At the same time, for the public teachings that were translated, Rinpoche explains the main topics for each of the text's "Seven Vajra Points".
You also find a recording of Rinpoche's meditation advice and recitation of root text, and 5 talks where Rinpoche trains the aspiring translators in oral translation based on the text.
