Darjeeling,Budhist monastery

This is Budhist monastery where there is original text of Tibetan Book Of Death.
In the morning at 7am I heard chanting 'Om Mani Padme Hum'...from tape or cd:)
only 2 persons ,villigers ,were circulating around the temple..(2 monks are living there..)
I felt some emptiness...maybe this is Budha's message...emptiness
