His Holiness the Dalai Lama was in Tsuglakhang, the main temple in Dharamshala, to preside over the prayers for Vesak, a day honouring the birth, enlightenment, and passing of the Buddha. This day occurs on the full moon (the 15th day) of the fourth Tibetan lunar month. On this day the effects of positive or negative actions are multiplied ten million times.
