Yogapedia explains Prithvi
In addition to prithvi, the remaining four of the pancha mahabhuta include jal (water), agni (fire), vayu (air) and ether (space). According to ancient scriptures, the five elements are the foundation of the universe. The five elements are present in human beings as well. Balancing the five elements helps in the maintenance of physical and mental health. Ancient medical practices, such as acupuncture and Ayurveda, base their treatment on balancing the five elements.
