So nag is a large community situated in the pasture of gCan tsha County. There

were only lay tantrics in the gSas khang, but recently there are also some

monks from the community, but since the monks do not have a monastery, both lay

tantrics and monks practise togather in the gSas khang. No records seem to

exist about the history of the gSas khang. I visited it in 1996, but

unfortunately there was not any old tantric from whom one could get some

information on local history concerning the gSas khang. I hope to be able to

fill up this gap when this book appears in Tibetan edition in the future.
