Thapan concludes that the period reflected in the Vināyaka section of the Mānava-Gṛhyasūtra must have been between the end of the 3rd and early 2nd century BCE. She based this conclusion in part on the fact that in the Mānava-Gṛhyasūtra the Vināyakas are associated with various other beings, including three of the four Buddhist lokpālas (guardians of the quarters), as well as the deities Mahādeva and Mahāsena.
Thapan asserts that the era reflected in the Vināyaka segment of the Mānava-Gṛhyasūtra spanned from the end of the 3rd to the early 2nd century BCE. Her reasoning for this assertion included the connection between Vināyakas and other entities, such as three out of four Buddhist lokpālas (quarter guardians) and deities Mahādeva and Mahāsena, found in the Mānava-Gṛhyasūtra.
