FPMT is a very bad example of a Vajrayana student. As mentioned in the 50 Stanzas of Guru Devotion, all attainment comes from our guru. Therefore, we have to follow the instructions of our guru and never go against it. That includes not giving up the practice given to us by our guru.
As everyone knows Lama Yeshe was a very devoted Dorje Shugden practitioner. He propitiated Dorje Shugden regularly. Whenever he needs help, he would also ask Dorje Shugden for help. The manifestation of Kopan Monastery was mainly due to Dorje Shugden's kind assistance.
Unfortunately, after Lama Yeshe passed away, students in FMPT chose to give up Dorje Shugden practice just to be politically correct and be in the good book of the Dalai Lama. They have forgotten the kindness of their guru. It is very hypocritical of them to keep the statue of Lama Yeshe on the shrine and then gave up the precious practice given to them by Lama Yeshe.
It is bizarre for FPMT to keep Lama Yeshe statue on their shrine when they broke their samaya by giving up the precious Dorje Shugden practice that was given by their guru, Lama Yeshe. It does not make sense for a student to only accept one part of the guru's teaching but not the other part.
On top of that, they are calling Dorje Shugden practitioner as demon worshippers and little did they know, they are calling Lama Yeshe a demon worshipper since he is a strong Dorje Shugden practitioner himself. Since FPMT is founded by Lama Yeshe, that makes them a demon-worshipping centre naturally since the founder practices demon worshipping.
Hence, what FPMT is doing now is not logical and they are only doing it for their own benefit. When they do that, they have broken their samaya with their guru and the lineage blessings are gone. Whatever spiritual practices done in the centres will have no blessings from the lineage masters.
