Some experts regard Lakshmi as a pre-Aryan goddess just like Yakshis.
T.S. Subramanian says in Frontline, June 15 2012 issue:
"You will find them everywhere, as sculptured figures of women hanging from a tree laden with mangoes, on the gateways to Buddhist stupas, adjacent to Jaina tirthankaras as exquisite bas-reliefs on the rock faces of hills, in wayside shrines, as terracotta figurines and stucco idols, as beautiful bronzes elsewhere, and as murals in temples. They are yakshis, popular folk goddesses of pre-Aryan days who metamorphosed into protective deities during the time of the brahminical religion and later as female attendants of Jaina tirthankaras. Yakshis are also celebrated deities in the Buddhist pantheon.
The history of the yakshi cult in India is a fascinating one. Yakshi sculptures have been found in Mathura in Uttar Pradesh; Didarganj and Basarh in Bihar; Bhopal, Sanchi and Khajuraho in Madhya Pradesh; Ellora in Maharashtra; Udayagiri and Khandagiri in Odisha; Tiruppanmalai, Vallimalai, Anaimalai, Tirumalai, Samanamalai, Sithamur and Sitharal in Tamil Nadu; Aihole and Shravanabelagola in Karnataka; and Nagarjunakonda, Kondapur, Peddapur and Amaravathi in Andhra Pradesh. About 50 bronze statues of yakshis have been found in different parts of India..."
