Wikipedia Trails: From Yaksha

Example of a Preta 1. Yaksha : I read about Yakshas in one of my peers' posts. I really though that these spiritual beings were interesting as they are able to shape-shift. I also learned that there are darker versions of Yaksas called bhuta. 2. Bhuta : These are supernatural creatures as well. There are bhutas in every religion; however, they are all represented differently. In the Indian culture, bhutas are restless souls prohibited from entering heaven or hell. 3. Bhuta led me to Pretas : Pretas are invisible mummies that usually travel with demons. These Pretas are usually reincarnated into another body, but they cannot eat or drink. 4. Akasha is the term that encompasses all of the elements and beings from which everything thing is made in the Hindu culture. Akasha means sky and is depicted as a fifth element, sound.
