Пема Лингпа
As phenomena of nature, all lakes in Bhutan are believed to be inhabited by spirits. A handful of lakes in Bhutan are particularly sacred, most often connected to lives of Buddhist saints Guru Rimpoche and Pema Lingpa. For example, Membar Tsho ("Burning Lake"), in the Tang Valley near Bumthang, is heavily associated with Guru Rimpoche, who brought Buddhism to Bhutan and discovered his first terma in the lake in 1475.
