Kukai: The Mandala Man
The city of Chang’an, the capital of the Tang Dynasty, was full of bustle. The wide streets were filled with the constant voices of people passing by, and merchants from all over the world displayed their goods. Kukai, too, was one of those who arrived here.
He was 31 years old. A young monk sent from Japan as a Japanese envoy to the Tang Dynasty, Kukai was in search of the profound teachings of esoteric Buddhism in the land of Tang. He had been devoted to Buddhism since childhood, and his curiosity knew no bounds, but he had not yet had the opportunity to come into contact with the essence of esoteric Buddhism. Therefore, he was betting everything on his studies in Chang’an.
One day, Kukai heard the name of a master of esoteric Buddhism, Huiguo. He was a renowned teacher known to everyone in the Buddhist world of the Tang Dynasty, and only a limited number of people were able to receive his teachings. However, Kukai did not hesitate to knock on his door.
Huiguo glanced at Kukai as he stood in front of the gate, and quietly invited him in. There must have been something about Kukai’s deep gaze and quiet determination. Thus began the relationship between master and disciple.
For the next three months, Kukai practiced day and night under Huiguo. The teachings of esoteric Buddhism are profound and go beyond words and theories, and it is said that once understood, their power is infinite. Huiguo generously imparted all of them to Kukai, who also tried to absorb them all.
Eventually, Huiguo called Kukai to him. His teacher quietly told him, “You are the teacher of Shingon Esoteric Buddhism. From now on, you will protect and spread these teachings.”
Kukai bowed deeply and, with gratitude to his teacher engraved in his heart, set off on his journey back to Japan.
In 806, Kukai returned to Japan. Huiguo’s teachings were firmly rooted in his heart. After returning home, he immediately began working to spread the teachings of esoteric Buddhism. He traveled to the sacred mountains and eventually arrived at Mount Koya. It was there that he found the ideal place he had imagined. Kukai climbed steep mountain paths to establish Kongobu-ji Temple, which floats in the mist. It was here that he established the teachings of Esoteric Shingon Buddhism and spread its light throughout Japan.
His teachings quickly captured the hearts of the people, and many disciples gathered around him. Kukai came to be revered as more than just a monk, but as an angel of the gods.
Time passed, and even after Kukai passed away, his teachings continue to live on in the hearts of the people. Kongobu-ji Temple on Mount Koya is still revered by many believers as a holy place where his spirit resides.
