The Mahamayatantra (abbr. MMT) is classified by Bu-ston as a yoginitantra. This tantra consists of three chapters and has two other titles, Paramaguhya and Mahaguhya. Ratnakarasanti (ca. 10c. -11c.) wrote a commentary on this tantra, entitled Gunavati. According to his commentary, the fact that the opening word is “atha” indicates that this tantra is a kind of akhyatatantra or uttaratantra (explanatory or supplementary tantra). In the present paper, I try to establish the relationship between the MMT and the Devimahatmya (abbr. DM), a basic Hindu text of worship of the Goddess, through the analysis of the word “brahmanda” in the MMT (chap. 1, verse 4) and in the DM and of some adjectives used to describe the deity, Mahamaya (MMT chap. 1, verse 4-6). According to my hypothesis, the MMT was composed between the eighth and eleventh centuries.
