In 2004 while visiting Tenerife, Khenpo Rimpoche challenged me to a short debate. Like a sabre cutting through confusion, he started this unexpected moment with a pregnant dharma question about doubts, which stopped my breath and mind. Grasping for air, I looked straight into the accumulation of knowledge and meditation experience he had fostered all these years, and answered in accordance with the teachings on emptiness. He laughed and started his recitation of some traditional verses with a loud 'la- me', which I thought meant that he did not agree, but he was so pleased and the moment so striking that I had to let go.
