Animistic traditions
Buddhist traditions

All of the above

The correct answer is: d) All of the above.

Ritual chants and songs invoking deities are an important part of the spiritual practices of many religions and cultures around the world. In animistic traditions, for example, it is believed that all objects in the natural world have a spirit or soul, and so rituals are performed to appease these spirits and ensure their goodwill. In Buddhist traditions, chanting is often used as a way to focus the mind and achieve a state of meditation. And in the Donyi-Polo faith, which is practiced by the indigenous people of Arunachal Pradesh in India, ritual chants and songs are used to communicate with the gods and goddesses of nature.

Ritual chants and songs can be used for a variety of purposes, such as to heal the sick, bring good luck, or ward off evil spirits. They can also be used to express gratitude to the gods and goddesses, or to ask for their guidance and protection. In some cases, ritual chants and songs may be accompanied by dancing, drumming, or other forms of ritual activity.

The use of ritual chants and songs is a powerful way to connect with the spiritual world. By chanting or singing, we can open ourselves up to the divine and experience a sense of peace, joy, and connection.
