法鼓山
In the Chan lineage of Sheng Yen, a "Dharma heir" receives the dharma transmission based on his or her selfless administrative contributions to Dharma Drum Mountain and practice of Chan. However, a Dharma heir may not have had a personal experience of self-nature or Buddha-nature, the nature of śūnyatā, in which case the person would also receive "yinke" (Jp. inka shōmei), the seal of approval. Among the Dharma heirs, there are only a few who have both Dharma transmission and yinke.
