1Enakshi Ganguly = ""According to Jagdish Narain Tiwari and Dilip Chakravati, the Matrikas were existent as early as the Vedic period and the Indus Valley civilization. Coins with rows of seven feminine deities or priestesses are cited as evidence for the theory. A Hindu text known as theRigveda (IX 102.4) speaks of a group of seven Mothers who control the preparation of Soma, but the earliest clear description appears in some layers of the epic Mahabharata (dated to 1st century AD). Wangu believes that Matrika description in Mahabharata, is rooted in the group of seven females depicted on Indus valley seals. It was assumed that the people locally worshipped these goddesses, such an example is also described in Zimmer Heinrich book The Art Of Indian Asia, about the seven shrines of seven Mother Goddesses worshipped locally. By the fifth century, all these goddesses were incorporated in mainstream orthodox Hinduism as Tantric deities."Source: https://en.wikipedia.org/wiki/Matrikas"
