Ancient beliefs of the Illyrian tribes which inhabited Bosnia and Herzegovina remained present in folk beliefs, mostly connected to the cult of water healing, in which the god Bindu is clearly manifested. When one analyses the folk cult of healing and the practice of it, which is essentially pagan in nature, then it is difficult to explain how that ancient system managed to survive in Bosnia especially in the midst of a strong expansion of Christianity and later Islam?! However, the answer should be sought in the fact that Christianity, especially after the appearance of Bogomils, or Islam had enough influence to fully assimilate the Bosnian people and to fully disengage them from the ancient Illyrian religion. And that it is true is perhaps best shown by the cult of god Bindu.
As it is known god Bindu was the god of springs of the Bosnian Illyrians whose spring-temples were found all over modern Bosnia and Herzegovina and the neighbouring Croatia. One of the best preserved holly places was found in Privilice near Bihać which is located in nature, next to a spring. At that location dozens of dedicated sacrifices to Binud were excavated, as well as a chapel with numerous animal bones sacrificed in his honour.
In the ritual practice of pilgrimage towards springs one can notice the influence of three religious cults of the Bosnian Illyrians: cult of the sun, cult of the moon and cult of Bindu.
Cult of the sun: the largest number of holly and salutary springs are located on the east side of the settlement. One would visit it exclusively at dawn, before sunrise, in order to pray, wash one's face and drink water. In such a way the diseased would expect the blessing of the sun which would shine the light and warmness on the person once it rose from the east.
Cult of the moon: the holly springs were visited in the first week of the new moon, precisely on odd days i.e. Monday, Wednesday, Friday and Sunday.
Cult of Bindu: after washing their faces and drinking water or placing it into vessels and carrying it home, the diseased would leave some money next to the streams, usually coins, food, eggs or they would hang some of their clothes on the nearby branches.
In the mentioned descriptions of rituals one can notice influences of three deities, which could point to the fact that Bindu was the son of the sun god and moon goddess and as their son he represented the perfect example of vitality and health which gives life and defeats evil, in this case over diseases. The sun that would appear in the east in the morning, according to folk belief the sun was "born", and the first seven days after the appearance of the new moon undoubtedly point to the idea of renewal of life energy, health and generally luck and prosperity. The sick would ask for blessings from the heavenly deities who again resurrected in their eternal cycles and the manifestation of their divine power was exactly the water over which Bindu had patronage and power.
