Life
Dhṛṭaka was the son of a wealthy brahmin. After ordaining as a Buddhist monk, he traveled to Mathura where he trained under Upagupta. Under his teacher's guidance, Dhṛṭaka received the sevenfold instructions and achieved arhatship.

According to tradition, Dhṛṭaka proselytized extensively, successfully introducing Buddhism to the Tokharians in central Asia. In the lineage of Chan Buddhism, he traveled to Madhyadeśa, where he converted Micchaka and his 8,000 disciples to Buddhism.
