 If a man sees another male devotee whom he does not know, he will address him as "Prabhu".It is also appended after a devotee's name, for example "Madhava Prabhu".In Indonesia, especially in Balinese, Javanese, and Sundanese culture, the term "Prabu" is used as a part of royal titles, especially to address Kings such as Prabhu Siliwangi, Prabu Kiansantang (the son of Prabu Siliwangi), etc.
