Yijing, formerly romanized as I-ching or I-tsing, born Zhang Wenming, was a Tang-era Chinese Buddhist monk famed as a traveller and translator. His account of his travels is an important source for the history of the medieval kingdoms along the sea route between China and India, especially Srivijaya in Indonesia. He also gave accounts of the Gupta Period. A student of the Buddhist university at Nālandā, he was also responsible for the translation of many Buddhist texts from Sanskrit and Pali into Chinese.

The Mahāsāṃghika was a major division (nikāya) of the early Buddhist schools in India. They were one of the two original communities that emerged from the first schism of the original pre-sectarian Buddhist tradition. This schism is traditionally held to have occurred after the Second Buddhist council, which occurred at some point during or after the reign of Kalashoka. The Mahāsāṃghika nikāya developed into numerous sects which spread throughout ancient India.
