Yeah I noticed the stripes too like in the pic of the late Kyabje Dilgo Khyentse Rinpoche. Thanks.Oh, and the pandita hats (pointy ones) worn by khenpos,
if they are red-- worn by nyingma and kagyu scholas-- there
are stipes. The number of stripes indicate the areas of expertise--
1, 2 or 3 stripes scholar of Sutra, tantra and dzogchen.
