Buddha's light is one of the four wonders of Mount Emei, which is as famous as sunrise, sea of clouds, Buddha's light and holy light. This phenomenon has hardly appeared in other places, but it can be seen in Emei Mountain, which can appear more than 60 times a year on average, and sometimes even more than 80 times a year, so people call it "Emei Baoguang". For thousands of years, "Emei Baoguang" has enjoyed a good reputation at home and abroad, and the rendering of Buddhism has made it more legendary and mysterious, attracting many curious people. Therefore, it attracts many people to try to make a scientific explanation of the mysterious "Buddha's Light".
In history, the Buddha's light of Mount Emei has also been recorded very early. According to legend, during the Yongping period of the Eastern Han Dynasty, a herbalist named Pu Gong climbed the Jinding under the guidance of a fairy deer, and then he was surprised to find the Buddha's light. Later, under the guidance of a monk, I realized that Buddha's light was "auspicious in Pu Xian". Pugong built Puguang Temple (also known as Guangxiang Temple) in Jinding to worship Bodhisattva, which created the history of Buddhism in Emei Mountain.
Buddhists believe that only those who have a relationship with Buddha can see this light. They believe that the Buddha's light is the light of salvation and good fortune from the Buddha's brow. Emperor Kangxi of the Qing Dynasty also specially inscribed the word "Jade Brilliant Light" and presented it to Huazang Temple, the Jinding where Buddha's light often appeared.
Of course, these are all deified statements and have no scientific basis. Some meteorologists have studied this. Buddha's light is caused by the special geographical environment of Mount Emei, and it is the function of sunlight and people. Mount Emei Jinding is 3077 meters above sea level, standing side by side with the three peaks of Thousand Buddha Temple and Ten Thousand Buddha Temple, just like a pen. Sanfeng faces a cliff to the east, which is more than 2000 meters high. This unique terrain forms the unique "undersea cloud" of Mount Emei. In the "undersea clouds" of Mount Emei, the humidity in the air is very high, which provides sufficient "playing places" for sunlight. In the process of propagation, sunlight will spread through the edges or gaps of obstacles. When the clouds are thick, they will be reflected by water drops or other things in the depths of the clouds after being transmitted by sunlight. When this reflection passes through the surface of the cloud, it will be diffracted at the edge of the tiny water droplets, resulting in a colorful halo of ultraviolet and red. The arrangement of ribbons is just the opposite of the rainbow, so different monochromatic lights will slowly spread out and a colorful halo will appear in front of people. If the viewer happens to be in a straight line with the sun and the halo, a figure will be reflected in the halo, and the shadow will move when walking, so some tourists will mistake it for a bodhisattva.
