At Mithbáv in the Ratnágiri District holy persons such as Sanyásis are worshipped after their death by performing their anniversary ceremony every year. It is believed that spirits are mortal. Evil spirits such as munjas, etc., undergo a kind of transformation, and it is believed that this occurs at places like Narsoba's Wádi. [422] At Devgad in the Ratnágiri District ancestors are worshipped on their anniversary days, the manes being represented by pieces of Darbha grass and balls of boiled rice. [423] At Poladpur in the Kolába District a person whose father is alive but who has lost his mother's father, has to perform the Shráddha of that grandfather on the 1st day of the bright half of Ashvin (October). This Shráddha is called Duhitra. A person who has lost his wife has to perform the Shráddha for that wife on the 9th day of the dark half of the month of Bhádrapada. This day is called Ahev Navami. These different sorts of Shráddhas are observed only by the high class Hindus. The lower classes worship their ancestors on the last day of the month of Bhádrapada by preparing a ball of boiled rice or flour, and putting it out for the crows to eat. It is believed that spirits are mortal. The ceremony called Narayan Nagabali is performed when it is believed that the spirit of an ancestor is giving trouble to the family. When this rite is performed, the spirit is saved and the ailment ceases. It is believed that the spirits of the dead are sometimes reborn in children in the same family, and in such cases the names of the ancestors are given to their children by the people. [424] At Khopoli in the Karjat taluka of the Kolába District the form of worship of ancestors is similar to that of the ordinary Hindu deities. In the case of the worship of the deities the person performing the worship has to sit with his face towards the east, while at the worship of the ancestors he has to sit with his face towards the south. [425] At Chaul in the Kolába District, the tombs of Sanyásis, i.e., ascetics and Sádhus are worshipped on their anniversary days, and a great fair is held in their honour. The other ancestors are worshipped by the shráddha rites. The anniversary of the founders of the different sects is observed by their followers by a bhajan, i.e., singing songs in their own style and exhibiting the different insignia and flag of the sect as advised by their founders. [426] The people of Chidhran in the Kolába District believe that the period for which the soul has to remain in the spirit state depends upon the sins of the person, or the wishes which remained unfulfilled during his life time. It is not that all the spirits of the dead are reborn in children. The rebirth depends upon the good or bad deeds of the deceased. However, if the nature of any child suggests the nature of any dead person in the family, it is assumed that the spirit of the deceased has returned to the family. [427]
