Shloka 13
Cāturhotra as Inner Sacrifice (Yoga-Yajña) and Nārāyaṇa Recitation
स्पर्शेन स्पृश्यते यच्च घ्राणेन प्रायते च यत् । मन:षष्ठानि संयम्य हवींष्येतानि सर्वश:
sparśena spṛśyate yac ca ghrāṇena prāyate ca yat | manaḥ-ṣaṣṭhāni saṁyamya havīṁṣy etāni sarvaśaḥ ||
婆罗门言：“凡触所觉者，凡鼻所嗅者——既制御以心为首之六根，当尽以此等一切，悉作供献之酥酪（供物）而奉入祭中。”

Educational Q&A
The verse teaches inner discipline: control the mind together with the senses, and treat sensory experiences (touch, smell, etc.) as offerings—i.e., relinquish attachment and redirect perception toward a higher, ethical-spiritual aim.
A Brāhmaṇa is instructing about an inward form of sacrifice: instead of merely external ritual acts, one performs a ‘yajña’ through restraint of the mind-and-senses, offering up sensory engagements as oblations.
