许多古典神话小说描写佛祖、菩萨等出现时多有“笼罩着五色祥云”、“香气四溢、红光四射”等语。过去,人们一直把这些“祥云”、“红光”当做纯粹的神话,但至今一系列的科学发现表明,这些描述对人体来说并非完全虚构。据现代科学研究,年事较高的老人,患有疾病的人和大量吸烟的人,身体内都能发出一种极其微弱的光。那么,这究竟是怎么回事呢? Many classical myths and novels describe the Buddha, Bodhisattva, etc. appear when there are many “covered with colored clouds”, “fragrance overflowing, red”. In the past, people have always regarded these “clouds” and “red light” as pure myths. However, a series of scientific discoveries so far show that these descriptions are not completely fictitious to the human body. According to modern scientific research, elderly people with higher age, people with diseases and people who smoke a lot, can emit extremely weak light in their bodies. So what is going on?
