One of the things that surprises visitors to Kandy is the four devale — temples dedicated to Hindu deities — standing directly within the sacred precinct of the city's most important Buddhist complex. Far from being an anomaly, this arrangement reflects something fundamental about how religion works in Sri Lanka: the boundaries between Buddhism and Hinduism have always been more porous here than the textbook categories suggest.
The four guardian deities venerated at these shrines are Natha, Vishnu, Kataragama and the goddess Pattini. Each has its own mythology, its own priests (called kapurale or basnayake nilame depending on the shrine) and its own ritual calendar. Significantly, the worshippers are largely Sinhalese Buddhists, not the Tamil Hindu community — which means that the majority ethnic and religious group in Sri Lanka routinely venerates deities from a different tradition, without any apparent sense of contradiction.
This is explained partly by the role these deities play in Sri Lankan cosmology: they are understood not as rivals to the Buddha but as powerful protector-figures, lower in the cosmic hierarchy than the enlightened Buddha but capable of intervening in worldly matters — health, prosperity, protection from harm — that the Buddha, having transcended the world entirely, does not concern himself with. You pray to the Buddha for wisdom and liberation; you ask the gods for help with your exam results or your failing business.
All four guardian deities feature prominently in the Esala Perahera procession, each with their own section. Vishnu's devale is particularly ancient and the most visited. The Pattini shrine venerates a goddess unique to Sri Lanka and South India, associated with chastity, healing and protection — her myth cycle, the Cilappatikaram, is one of the great works of classical Tamil literature.
Walking through the Kandy devale complex alongside the Dalada Maligawa takes perhaps twenty quiet minutes, but the questions it raises about religious identity, coexistence and the limits of category tend to stay considerably longer.
