The creator of this thangka is blinded by his hatred and not seeing things clearly. What Ensapa said is really accurate. The thangka does not make any sense. The Dorje Shugden under Guru Tragphur is wearing monk robes and also holding a Vinaya staff. The monk robes and Vinaya staff represents the vows and Vinaya that sangha is holding which came from Buddha Shakyamuni.
It is not appropriate for Guru Tragphur to be stepping on these 2 items because it will be extremely disrespectful. How can a Buddha disrespect the Dharma? That does not make any sense. Anyone that understands the iconography will be able to tell that this thangka is fabricated and it certainly will not be authentic.
It is unbelievable that someone will go to the extent to create a totally false thangka just to put Dorje Shugden down. They deviated from their lineage when they simply change the iconography of those deities which does not match with the scriptures. This happened once during His Holiness the 16th Karmapa visit to the open ceremony of a Nyingma monastery. When the 16th Karmapa passes by a new statue of Dorje Drolo who is a wrathful emanation of Guru Rinpoche, he gives the instruction to remove the statue because Dorje Drolo is stepping on a being that resembles Dorje Shugden which is inaccurate.
Many people like to be in the Dalai Lama's good book, so when the ban was imposed, some immediately go along with the Dalai Lama and do funny things. Some paint a thangka with a wrong iconography like this, some produce talisman to protect themselves from Dorje Shugden. If Dorje Shugden really is a spirit, what is so special about him that they have to do something just for him?
The best way to get rid of a spirit is to subdue him or do it like how Guru Rinpoche bound Nechung with an oath and made him a Dharma protector. There are so many high Lamas in all the Tibetan lineages, there must be one who can do the job! Why is that no one is doing it? A spirit can never be more powerful than the Buddha. If that is the case, why do we take refuge in the 3 Jewels.
It is so obvious that the ban was imposed unlawfully and the reasons the CTA gave are so illogical but because most people want to be in the Dalai Lama and the CTA's good book, they just follow blindly. Not only the Tibetans are like that, Tibetan Buddhists all around the world are like that too. Buddhism is supposed to be a religion with logic but the followers don't have any logic sense.
