Shiva’s mount is the sacred bull Nandi, and is said to live on Mount Kailasa in the Himalayas.
Although Halloween is not a Vaisnave holiday, it is being celebrated here in the West today. So we wanted to do a post from the pages of Srila Prabhupada’s books where there is mention of Ghosts and Witches etc. Actually Ghosts are a very real entity as the following texts from the Bhagavad-gita and the Srimad Bhagavatam imply.
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…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. Lord Śiva, being very kind to the ghosts, sees that although they are condemned, they get physical bodies. ( from purport to SB 3.14.24)
Those who worship the demigods will take birth among the demigods; those who worship ghosts and spirits will take birth among such beings; those who worship ancestors go to the ancestors; and those who worship Me will live with Me. (Bhagavad-gita 9.25)
