|From Hompi, Karṇataka|
In Indian religious and popular culture (though not in the philosophical reflection, I am inclined to think, see here) one similarly sees that one believes and believed in a variety of intermediate beings occupying each inch of land, earth and sky. The anthropologist Gilles Tarabout underlined this aspect in (at least) two of his papers. In one of them, published in RiSS and dealing with astrology in Kerala, Tarabout refers of how astrologers consulted by the committee of a temple regularly describe the temple as full of presences, part of which may need to be pacified.
In his recent speech at the conference on The Human Person and Nature in Classical and Modern India, Tarabout has repeated how "No place is free of occupants". Thus, while building something new, one needs to pacify these powers, especially insofar as several of them may be malevolent or at least ambivalent. Among the former are listed bhūtas, pretas (which are described by Tarabout's informants as malevolent due to their untimely death) and are violent deities, whereas among the latter are yakṣīs which are dangerous female beings, honoured as goddesses and thought of as the spirits of unmarried dead girls. Only the serpent-deities may remain and most gardens in Kerala have a spot which is left wild and where nāgas are thought to dwell. In an interesting document of the Colonial time reported by Tarabout a spot of land is said to be sold together with cobras, the sky above, the underground with its treasures and the corresponding part of hell…
I guess that ancestors (pitṛs) would instead be counted among benevolent creatures. Do you have any evidence of the contrary?
Furthermore, this background assumptions partly explain also why non-theistic religions such as Buddhism and Jainism did not feel the need to deny the existence of nāgas, devas, and so on, and why monotheistic Indian religions acted in the same way: these beings were not the object of a specific faith but were just part of the description of the world as it is. Thus, they did not compete with the Buddha, the Jina, Viṣṇu, etc., for their believers' hearts.
