Hello Losang Tenpa and Harry Nephew,
A monk friend emailed me the picture of this Gyalchen Tendoe as he calls it. He said that it is very rare that monks are able to make these anymore. From the picture, I can see that it is basically a representation of Dorje Shugden's mandala with the Dorje Shugden and his 32 in his entourage on the ground floor, Setrap on the first floor and Buddha Amitabha on the 2nd floor.
I am guessing because I can't really see the image within this divine mandala. I heard that the previous incarnation of Kyabje Zong Rinpoche instructed and made sure a Gyelchen Tendoe was made just before he passed into clear light. I am not sure what's the significance but i am sure it is to house Dorje Shugden's energy within that particular area.
