Lord Śiva, or Rudra, is the king of the ghosts. Ghostly characters worship Lord Śiva to be gradually guided toward a path of self-realization. Māyāvādī philosophers are mostly worshipers of Lord Śiva, and Śrīpāda Śaṅkarācārya is considered to be the incarnation of Lord Śiva for preaching godlessness to the Māyāvādī philosophers. Ghosts are bereft of a physical body because of their grievously sinful acts, such as suicide. The last resort of the ghostly characters in human society is to take shelter of suicide, either material or spiritual. Material suicide causes loss of the physical body, and spiritual suicide causes loss of the individual identity. Māyāvādī philosophers desire to lose their individuality and merge into the impersonal spiritual brahmajyoti existence. Lord Śiva, being very kind to the ghosts, sees that although they are condemned, they get physical bodies. He places them into the wombs of women who indulge in sexual intercourse regardless of the restrictions on time and circumstance. Kaśyapa wanted to impress this fact upon Diti so that she might wait for a while.
