Overexploitation of natural resources decreases the environment quality. One of the efforts to bring back sustainability and sanctity of nature (spiritually) is holding the ceremony called Karya Agung (big ceremony)  Pangurip Gumi. 
<p>To hold a big ceremony, Bali people must do yasa kerti (praying) to prepare both physics, especially spirituality, purity of heart, thinking, speaking and behaving and avoid doing such negative things that can tarnish the sanctity of the ceremony.

According to I Wayan Tontra, head of PHDI (Indonesia Hinduism Society) of Tabanan, as quoted “Karya Agung Pangurip Gumi intends to arouse the energy of the earth. Like a handphone, it needs to recharge, so the earth and/or nature must be given the energy through the ceremonies”.
