When Karmapa was in China, he performed miracles for 100 days. On the first day, a shimmering five-colored cloud appeared, which expanded and contracted many times and radiated like the wish-fulfilling jewel. A stupa, which contained holy relics, radiated as shiny as the full moon, and exactly above the place where Karmapa was, two golden light garlands towered. On the sixth day clouds could be seen that glistened like begging bowls and filled the whole sky. In a southwestern direction, arhats with their retinue appeared. On another day flowers fell from the sky, some fully blossoming, others as buds. Their stalks and blossoms were like crystal and hovered around. Above the temple where Karmapa had prepared the power field for the empowerment, a five-colored rainbow appeared. Beings with begging bowls and pilgrim sticks appeared. During the eighteenth night, people saw two lights of strong red color, which brightened the whole sky. From far away, gods came close, adorned with precious jewels and riding on blue lions and white elephants. The emperor was so impressed that he honored Karmapa as a Buddha and bestowed upon him the title, “Great Precious King of Dharma.” He ordered that all these miracles should be painted on silk rolls by his best artists; these were later sent to Tsurphu. This was also the time when the emperor asked the 5th Karmapa to give him a replica of the power field above his head - the Black Crown, made from the Dakinis’ hair – so that everyone would be able to witness it. The Karmapa agreed and blessed the hat, which was decorated with ornaments made of precious jewels and gold.
One day the emperor told Karmapa that there exist too many Buddhist lineages; there should only be the Karma Kagyü lineage. He probably offered to send regular armies to unify Tibet under the Karmapa but Dezhin Shegpa declined this rather non-Buddhist proposal. Karmapa explained that he did not wish that and that this is of no benefit. The people needed different kinds of teachings, moreover all lineages are one big Buddhist family. The emperor understood Karmapa’s advice and stopped his troops. Later the emperor became a great bodhisattva.
