Shloka 23
Adhyāya 214: Tapas Redefined—Perpetual Discipline, Hospitality, and the Ethics of Eating (तपः-निरूपणम्, विघसाशी-अतिथिप्रिय-धर्मः)
महर्षिर्भगवानन्रिवेंद तच्छुक्रसम्भवम् । त्रिबीजमिन्द्रदैवत्यं तस्मादिन्द्रियमुच्यते
mahārṣir bhagavān atrir veda tac chukra-sambhavam | tri-bījam indra-daivatyam tasmād indriyam ucyate ||
ビーシュマは言った。「尊き大聖アトリ（Atri）は、その生殖の力の起こりと行路を知っている。彼はそれに三つの因があると宣言する—心を運ぶ（脈道）、サンカルパ（決意）、そして食である。この力を司る神はインドラである。ゆえにそれは『インドリヤ』（indriya）—インドラに属するもの、インドラの主宰下にある機能—と呼ばれる。」

Educational Q&A
The verse links bodily potency and the functioning of faculties to three supports—mind-channel, intention, and nourishment—implying that ethical self-mastery involves regulating thought (saṅkalpa) and diet, since the senses (indriyas) are governed under a higher order symbolized by Indra.
In Bhishma’s instruction during the Shanti Parva, he cites the authority of the sage Atri to explain the origin and classification of ‘indriya,’ giving a doctrinal-etymological account that connects physiology, psychology, and divine governance.
