The ancient Indian scriptures known as the Vedas are foundational texts of Hinduism.
Among the four Vedas, the Ṛgveda is specifically organized into distinct sections called Maṇḍalas.
The Ṛgveda consists of 10 Maṇḍalas, which are collections of hymns (sūktas) dedicated to various deities.
Sāmaveda, Yajurveda, and Atharvaveda have different structural organizations and are not primarily divided into Maṇḍalas.
Therefore, the Veda divided into Maṇḍalas is the Ṛgveda.
