I found this intriguing post by a NKT resident teacher Gen Kalsang Phagpa on facebook posted on Lama Zopa Rinpoche's wall. I find what he has to say is very valid and true. Those questions I would ask myself to Lama Zopa Rinpoche with great respect as he is a great teacher upholding the Mahayana teachings, just why not Dorje Shugden which he received from high and eminent masters of our time such as Kyabje Trijang Rinpoche and Kyabje Zong Rinpoche?
Below's a screenshot of that post. If you are on Lama Zopa's fanpage, do add on to our support for Dorje Shugden, we have to compassionately point this out~!
