The Bey Langdra is a sacred site highly revered in Wangdue Phodrang. Guru Padmasambhava saw in his vision the sufferings the people in the locality endured because of drought and powerful malignant spirit. Guru Rinpoche meditated & conquered the spirit which turned into a red bull to oppose the Guru. The spirit was subsequently turned into a protecting deity of the place & numerous treasures the Guru concealed. Thus, the name Bey Langdra means the rock/cliff of the bull where treasure teaching is hidden to be discovered in the future.
The great Terton Dorji Lingpa discovered one of the most profound treasures from the site.
