There are many, but the list doesn't include Tibetan women
such as Jetsun Kushok, Khandro Rinpoche (who is a nun but belongs
t a family lineage of ngakpas), Sangyum Kamala
(who visits the west sometimes).
Then there's other westerners--
Akhon Lhamo, Lama Yeshe Wangmo, Sangye Khandro.
Jetsunma Tenzin Palmo, a nun...
Some of the female Lamas are qualified at the highest levels
of study and practice.
