The Druk Gawa Khilwa nunnery in Kathmandu, Nepal.
In 2008, the leader of the 1,000-year-old Drukpa lineage, His Holiness The Gyalwang Drukpa, decided to encourage his nuns to learn self-defence.
His simple motive: to promote gender equality and empower the young women, who mostly come from poor backgrounds in India and Tibet.
Dressed in traditional maroon robes modified in the style of karate uniforms, the nuns’ smiling faces conceal an incredible energy and strength.
