In the Tibetan tradition there is a wonderful land called Sambhala: a kingdom inhabited by sages, hidden between snowy mountains somewhere in northern India and the Tibert. This book offers a vision of this land through ancient texts and modern testimonies, among which the first translation into Castilian of the Kalapavatara and the comparison made between this work and the Life of Apollonius of Tiana de Filóstrato stand out.
