O King! Viśvāmitra had 101 sons, of whom the middle one was known as Madhucchandā. In relation to him, all the other sons were celebrated as the Madhucchandās. He had one hundred and one sons (eka-śatam). Śruti says tasya ha viśvāmitrasyaika-śataṁ putrā āsuḥ paṣcāśad eva jyāyāṁso madhucchandasaḥ paṣcāśat kanīyāṁsaḥ: Viśvāmitra had 101 sons, fifty of which were older than Madhucchandā and fifty younger. (Ṛg Veda, Aitareya Brāhmaṇa 7.15.7) They were all called by the same name since he was the principal in the group. When placing bricks for a sacrifice one brick is purified by the famous prāṇa-bhṛta mantra and is called prāna-bhṛt. All other bricks are called prāṇa-bhrt since they are related to the principal brick.
