Ever since then the annual rites of great accomplishment for the deities Vajrasattva, Palchen Heruka, and Vajrakilaya have been held in this temple for the well-being of the country under the patronage of Kesang Choden Wangchuck.

There is a belief that the two orange trees in the courtyard of Kyichu Lhakhang bear fruit throughout the year.

The story of the foundation of these temples by the Tibetan King is so well known to the Bhutanese that, according to historian Karma Phuntsho, Bhutan's history effectively begins with this event.

[1] Kyichu Lhakhang is believed to have been a smaller structure when the Tibetan King Songtsen Gampo erected this sacred building in the year 659, but a number of Buddhist saints and gurus added to the site until it became the spectacular temple it is today.

[3] The annual three-day festival, Kichu Zangchoe Moenlam or the “Rite of Great Accomplishment” is performed from the 22nd day of the 8th month of the lunar calendar.
