The Hyang, which is represented in both Balinese and Java mythology as the Supreme Being, is considered to be either divine or ancestral. It can be regarded as a symbol of the Supreme Being in folk religions such as those of the Sunda Wiwitan, Kejawen, Cigugur Sundanism, and Kapitayan. In addition, other religions such as those of the Balinism and Javanism have also regarded this spiritual entity as a part of their own traditions.

The place where Hyang is located is called the Kahyangan, which literally means "the abode of Hyang," or "part of Hyang," according to Old Javanese tradition. According to old Javanese manuscripts, Hyang refers to the concept of omnipotence and  also means "the powerful." This term is commonly used in the Sunda Wiwitan spirituality to refer to the powerful.

Balinism, refers to the Hyang as a personal form that has supernatural powers. It is believed that his arrival in a person's life provides them with great happiness and satisfaction. In Indonesia, people commonly refer to the term Hyang as referring to the creator, beauty, or all existence.

The Hyang's origins can be traced back to the origins of various words and phrases such as rahyang, sakyang, and dayang. In modern times, the term hyang is often used to refer to gods and certain haunted places. The word tiyang, which literally means "person," is believed to have come from the words hyang and ti.

The word priangan, which literally means "the abode of the noble Hyangs," is often used to refer to the place where the noble family lives. Dieng Plateau in Central Java is also derived from the combined words di-hyang and dah-hyang. Gunung Padang in West Java is from the word dah-hyang, which literally means "the sacred place of Hyangs." The word sembahyang, which literally means "worshipping," is a derivative of the Islamic shalat ritual.
