Hello Lineageholder and emptymountains,
I can't address the ban about performing Lama Chopa at Bodh Gaya, as I know nothing about that, but I can let you know that at my Dharma Center (which operates under the patronage of His Holiness the Dalai Lama) that we practice the Lama Chopa every month. We perform it in both Tibetan and English.
I can also state that at our center, that Lineage Gurus such as Pabongka Rinpoche and Trijang Rinpoche are not removed from prayers and paintings.
I can't address anyone else's Center, but our Center operates very strictly according to His Holiness' guidelines.
Best regards,
Pup Clayton
