कामबन्धन-निवृत्ति तथा शान्तिलक्षण-उपदेशः | Release from Desire-Bondage and the Marks of Peace
प्राणी वा यदि वाप्राणी संस्कारं यजुषाहति । न दिवा प्रस्वपेज्जातु न पूर्वापररात्रिषु,यज्ञमें यजमान एवं हविष्य आदि सबका यजुर्वेदके मन्त्रसे संस्कार होना चाहिये। गृहस्थ पुरुष दिनमें कभी न सोये। रातके पहले और पिछले भागमें भी नींद न ले
prāṇī vā yadi vāprāṇī saṃskāraṃ yajuṣāhati | na divā prasvapet jātu na pūrvāpararātriṣu ||
Vyāsa said: Whether the offering is living or non-living, it should be duly consecrated with Yajurvedic mantras. A householder should never sleep during the day, nor should he indulge in sleep in the early or the latter part of the night—thus maintaining the disciplined vigilance expected of one engaged in sacrifice and righteous household life.
व्यास उवाच
Ritual life and household dharma require disciplined conduct: offerings must be properly consecrated with Yajurvedic mantras, and the householder should cultivate vigilance and restraint by avoiding daytime sleep and avoiding sleep in the early and late portions of the night.
Vyāsa is laying down prescriptive norms of conduct connected with sacrifice and the gṛhastha stage—how ritual items are to be sanctified and what personal discipline (especially regarding sleep) is expected of the yajamāna/householder.
