The xiii DL restored the Potala and Ganden not as an offering to Venerable Dorje Shugden but following his advice, uttered through the Dungkar Gonpa's oracle and transmitted to him by HH Domo Geshe Rinpoche Ngawang Kelsang. Dorje Shugden adviced the xiii DL to do that in order to prevent some serious foreign threats to Tibet.
