Zen traces its lineage to Bodhidharma — the semi-legendary Indian monk who brought the transmission of awakening to China in the 5th-6th century CE. The famous story: Bodhidharma sat facing a wall for nine years. When the Emperor Wu asked him what merit he had accumulated through building temples and supporting monks, Bodhidharma replied: "No merit whatsoever." When asked what the highest truth of Buddhism was, he replied: "Vast emptiness — nothing holy." When asked who was speaking, he replied: "I don't know."
These exchanges capture the Zen spirit perfectly — the refusal to play the game of conventional religious discourse, the insistence on direct pointing to the actual nature of reality rather than elaborate doctrinal description. The line of transmission from Bodhidharma through the Chinese Chan masters — culminating in the Sixth Patriarch Huineng (638-713) and the explosion of the classical period of Tang dynasty Chan — produced some of the most remarkable spiritual literature in any tradition: the Platform Sutra, the Blue Cliff Record, the Gateless Gate.
