Even setrap has shown his displeasure at the activities of the monastery for printing the fliers, and indirectly giving them a warning to follow HHDL's advice and not be too overzealous about it when the monks cannot speak too much or else they would be kicked out of Drepung. The protector will always oversee these monks even if they cannot do his practice openly but they can still find a way to supplicate him to keep the connection. And that to me is nothing short of the perfection of determination as they practice Dorje Shugden so that more people can benefit.
I think there is a difference between following a rule to show obedience and overdoing it. Perhaps the monks of Drepung should really reflect on what they have done, and whether or not it was necessary to go to that extent.
However, knowing the course of events, perhaps it is related to His Holiness' actions during the opening ceremony of Drepung Loseling monastery in Mundgod, Karnataka State in January 2008, and the Drepung monks are trying their best to 'please' His Holiness.
His Holiness was quoted to say: “With strong emotion, Samdhong Lama accused Shugden devotees, saying that they have made open and overt contact with the People's Republic of China.” His Holiness added that he thinks it is very difficult for the monks to remain like fish and tadpoles together in the three monasteries of the Gelug Tradition.
In the afternoon, the Dalai Lama convened a meeting in Drepung monastery, which was attended by Kolon Samdong Lama, Tsering Phuntsok, the Tibetan minister of Culture and Religion, abbots and ex-abbots. The Dalai Lama urged them to take action to clean up Shugden devotees. He reprimanded the abbots of Jangtse and Shartse monasteries for not taking a rigid stand against Shugden devotees.
The Dalai Lama rebuked the Shartse abbot: "Shugden devotees are growing in your monastery. If you are this inept, you had better resign." The Dalai Lama also reprimanded the Jangtse abbot: “You said that the monastery is clean, but there are still some Shugden devotees. You must do better." Hence, perhaps to show that Drepung is 'clean', they had to do all that.
Attached below is a picture of the notice from Drepung Loseling. Why do they do that?
