व्यपोहनस्तवनिरूपण-प्रसङ्गे नक्तभोजन-शिवव्रतविधिः (वार्षिक-प्रतिमास-क्रमः)
उपवासात् परं भैक्ष्यं भैक्ष्यात् परम् अयाचितम् अयाचितात् परं नक्तं तस्मान् नक्तेन वर्तयेत्
upavāsāt paraṃ bhaikṣyaṃ bhaikṣyāt param ayācitam ayācitāt paraṃ naktaṃ tasmān naktena vartayet
ઉપવાસ કરતાં ભૈક્ષ્યજીવન શ્રેષ્ઠ છે; ભૈક્ષ્ય કરતાં અયાચિત (માગ્યા વિના મળેલું) શ્રેષ્ઠ છે; અયાચિત કરતાં નક્ત શ્રેષ્ઠ છે. તેથી નક્ત વ્રતથી જ વર્તવું જોઈએ.
Suta Goswami (narrating Śaiva vrata and niyama teachings within the Linga Purana discourse)
It teaches that purity of sustenance is part of Linga-pūjā: refining one’s intake from ordinary eating toward disciplined, non-possessive living (ayācita, then nakta) supports steadiness in worship and reduces pasha (bondage) born of craving.
By implying that the highest discipline is self-restraint offered to Pati, it points to Śiva as the Lord who liberates the paśu (individual soul) from pasha through inner detachment, not merely external austerity.
The verse highlights āhāra-niyama through the nakta-vrata (eating once at night), progressing via bhaikṣya and ayācita—practices aligned with Pāśupata-style renunciation and sense-control supporting japa and pūjā.
