These texts are distributed to Buddhist monks, nuns, and laypeople at the annual World Peace Ceremony, which Tarthang Tulku started in 1990 to bring the various Buddhist communities from across Asia to celebrate together at Bodh Gaya, in India. The World Peace Ceremony and the work of Yeshe De have and the Tibetan Aid Project have resulted in over 20 million texts being given away to practitioners in the Buddhist community over the last 18 years.
