Kalu Kumaraya, the Black Prince, is the demon of the lowland Sinhala pantheon most associated with the afflictions of women. Folk legend gives him a princely but ill-fated origin, after which he wanders as a yaka. He is compared by ethnographers to an incubus: he comes to women, and especially to girls at the threshold of womanhood, as a lover in pleasurable dreams, and is blamed for menstrual irregularity, troubled pregnancy and miscarriage. When a ritual specialist (edura) diagnoses his presence, the cure is an exorcism in which Kalu Kumara is drawn out and appeased with prepared offerings of rice, curries, breadfruit and fish, releasing the woman from his hold.
