There are three worlds of existence: the physical, subtle and causal, termed Bhūloka, Antarloka and Śivaloka. The Creator of all, Śiva Himself is uncreated.As supreme Mahādeva, Śiva wills into manifestation all souls and all form, issuing them from Himself like light from a fire or waves from an ocean.The universe ends at Mahāpralaya, when time, form and space dissolve in God Śiva.
