Thank you for sharing this great historical event here with all of us. It is very important as many of us do not know about what Lord Tsongkhapa has did in his lifetime although we are practicing his prayers. It is sad to see how Duldzin Dragpa Gyaltsen's actions for Dharma has been forgotten and wiped aside because of this ban. He has done so many great things for the Gelug lineage, yet not many people know who he is. More so even now, his emanation's (Dorje Shugden) practices are being banned. This is really no way to treat a great lineage master. Being forgotten for all the deeds he has done to benefit us.
