Works

Position

Kūkai distinguished the exoteric teachings, which the historical Buddha adapted to his listeners, from the esoteric teaching spoken directly by the cosmic Buddha Mahavairocana. The whole universe – the six elements of earth, water, fire, wind, space and consciousness – is this Buddha’s body, and all sounds and forms are his preaching. Through the three mysteries of body, speech and mind – ritual gestures, sacred formulas (mantra) and visualisation – the practitioner unites with the Buddha and can realise buddhahood in this very body. In The Ten Stages of Mind he ranked the teachings of his day, from Confucianism through Madhyamaka and Huayan, with esoteric Shingon at the summit.

Life & context

Kūkai was born in 774 in Sanuki province on Shikoku. He left the state academy to live as a wandering Buddhist ascetic. In 804 he sailed to China with an official embassy; in Chang’an the esoteric master Huiguo made him his heir. Back in Japan from 806, he founded the monastery on Mount Kōya and received Tōji in Kyoto. He died in 835; posterity honours him as Kōbō Daishi.
