Puja at Boudhanath

It's really exciting to live close to Boudhanath and witness these big meetings.
Since they have the meetings outdoor, next to the stupa, we are all invited to join.
Listen to the chanting.

So many monks and nuns had gathered for this occasion.

Here are the leaders.

You can see the hierarchy clearly. The leaders in the front, then the monks and nuns with an orange sheet and in the back they only have the marron sheets.
