The Square for Bathing the Buddha is the place in Mengle Temple for Dai people to celebrate big events such as the New Year, or the festivals marking the beginning and the end of the Buddhist Lent. The custom of bathing the Buddha originated in India, and later became a common activity among Theravada Buddhists when commemorating the anniversary of the Buddha’s Renunciation or His Enlightenment. At the same time, people bathe Buddha images in order to make merit or to receive the kind love of the Buddha. One Sutra says: “Now I have bathed all the Buddhas; I have purified my mind and accomplished an ocean of meritorious deeds; I have avoided the ignorance of this world, and contributed to lead us all towards Enlightenment”. At the same time, bathing a Buddha image can purify our selves. The water we use in the bathing is holy, and has the power to purify our mind from dirtiness and disgrace; to eliminate all suffering, unblock our vision, heal our wounds and diseases, and to make us happy. All Buddhists who have bathed the Buddha are blessed and can take refuge in the merit produced by this deed.
