The Dome of the Temple is similar to the one pictured here.
There are many Golden temples and pyramids surrounding the Central Dome in Shamballa.
The Dome of Instruction is a giant circular lecture hall where Sanat Kumara or Lord Buddha gathers masters from the 7 ray ashrams (all those in Shamballa) and instructs them on the Divine Plan/purpose. Sanat Kumara receives instruction from Galactic councils and then instructs those in Shamballa.
Sanat Kumara is busy with instruction but can split his essence many times. He can be privately contacted by incarnated initiates on earth while teaching inner plane masters at the same time.
Various channeling techniques can be used or Sanat Kumara can be contacted through using the medium of energy such as Reiki or Reconnective healing (heal yourself with energy with the intent of contacting Sanat Kumara for the purpose of ( ) for your highest and greatest good)
