Travelling monks and scholars ensured that the land never lacked in its cultural and religious dimensions. The Vajrayana sect of Mahayana Buddhism is the dominant form of the religion, with a mixture of the animistic Bon faith and ancient Hindu tantric practices. Both Central and Eastern Ladakh are predominantly Buddhist while Western Ladakh is mainly Shia Muslim. Ruling Muslim priests are known as Aghas who combine the secular and religious functions in their hereditary duties. The mosques and Imambaras here are attractive examples of Iranian and Saracenic architecture, but due to the strong Islamic injunction against any form of gaeity and celebration in all aspects of life, western Ladakh is sombre and subdued, though not lacking in any of the deeper human qualities
