The first tantric Kalachakra instructions delivered by the 11th Panchen Lama Bainqen Erdini Qoigyijabu formally started, with some 40 monks beginning a closed-door observance of Yidam, the Kalachakra deity, Thursday morning. The Kalachakra (the wheel of time) ritual includes a series of tantric teachings and initiations given by gurus to help Buddhists through the cycle of life. [Photo/Xinhua]
