Its a really well compiled library with main parts: buddhism, taoism, hinduism, hermetics, anthropology, philosophy, religion, spiritualism, parapsychology, transhumanism and ufology. There are mostly hungarian texts, but a lot of them have english translation. There are collected the works of visionary artists below "art" option. Well, you can find there works from buddhist and hindu art. enjoy :)
