Two Bhartriharis are known to India. One was a mystical grammarian who wrote an important linguistic treatise, the Vākyapadīya. The other Bhartrihari, a poet, left between two hundred and seven hundred poems. A Chinese Buddhist pilgrim to 7th century India, I-Tsing, noted the name Bhartrihari in his travel Journals. He heard that grammarian and poet were the same man.
