The Rabdey’s visit I understand is primarily to start and install a “sachu bumdre” or offerings to appease deities. This ancient buddhist ritual is performed to seek protection from natural calamities like floods, land slides and others by appeasing deities.
With the Lunana GLOF works underway, the Lam Neten hopes that this effort from the Rabdey would help the works run smoothly and also, reduce risks for settlements down stream in the Punakha valley and beyond.
The huge hydro power projects on the puna tsangchu with the source of the river being in Lunana would also be a focus as “sa chu bumdre” is normally performed at the source of rivers to avert risks as a traditional practise.
Interaction with the local communities there as they pass along would also greatly benefit the people. Laya has a lam from the dratsang in addition to another lam at a lungu community goenpa, however, for the lunaps it would be a welcome visit.
