Despite this, when the Tashilhunpo monks started hearing what seemed credible accounts that a incarnation of Gendun Drup had appeared nearby and repeatedly announced himself from the age of two, their curiosity was aroused. It was some 55 years after Tsongkhapa's death when eventually, the monastic authorities saw compelling evidence that convinced them the child in question was indeed the incarnation of their founder. They felt obliged to break with their own tradition and in 1487, the boy was renamed Gendun Gyatso and installed at Tashilhunpo as Gendun Drup's tulku, albeit informally.
