I recently received a letter from a friend at sera, here are some of the sad details of what is happening
The situation at Sera Mey is certainly very bad. The Dalai Lama has banned all Dorje Shugden practitioners from receiving meals at the monastery (you may remember that they all received three meals per day and these meals were sponsored by a (now deceased) ex-Abbot who ran a Dharma Centre in the USA), they are banned from attending Sera Mey pujas (the only source of 'income' for the vast majority of monks) and they have been banned from attending debates. In effect there is a schism in the Sangha and DS practitioners have been thoroughly ostracised by non-DS practitioners. All monks had to sign two things: (1) to say that they did not practise DS and (2) that they would not live together with DS practitioners.
I'm really not sure about the food situation. Some have their own cooking facilities, but those DS practitioners who live in the hostels will have problems. Also, the supply of gas cylinders for cooking is at best precarious, and are usually bought from the Sera Mey kitchens anyway.
You may remember that Pomra Khangtsen openly practised DS. Well, this Khangtsen has now been split into two with the largest Lharam and the largest Shagtsang voting with the Dalai Lama. The present Abbot is with this group.
Traditionally all Khangtsen monks receive Rupees 1,000 from sponsors at a special Losar puja and use this to pay for the holiday. It look as though they won't be getting this this year so it will be a pretty miserable celebration for them.
However, we have to remember mitapa (impermanence) and it may all change again (although it is highly unlikely). New DS monks had already been banned from enrolling at Sera Mey, and older students banned from taking the final exams.
