In the second year of the Tang Dynasty (AD 7 13), on the third day of the eighth lunar month, after Huineng, the sixth ancestor of Zen, died in his hometown, the great disciple Fahai hid his sixth ancestor in this pit for fear that people would fight for his true identity. Later, many disciples couldn't decide whether to worship Guo 'en Temple in their hometown or Nanhua Temple in Shaoguan (formerly known as "Baolin Temple"), and they all relied on the way of burning incense and asking their ancestors.
