When Kūkai reached China and first met Huiguo on the fifth month of 805, Huiguo was age sixty and on the verge of death from a long spate of illness. Huiguo exclaimed to Kūkai in Chinese (in paraphrase), "At last, you have come! I have been waiting for you! Quickly, prepare yourself for initiation into the mandalas!" Huiguo had foreseen that Esoteric Buddhism would not survive in India and China in the near future and that it was Kukai's destiny to see it continue in Japan. In the short space of three months, Huiguo initiated and taught Kūkai everything he knew on the doctrines and practices of the Mandala of the Two Realms as well as mastery of Sanskrit and (presumably to be able to communicate with Master Huiguo) Chinese. Huiguo declared Kūkai to be his final disciple and proclaimed him a Dharma successor, giving the lineage name "Henjō-Kongō" () "All-Illuminating Vajra".
