यक्षलोकमनुप्राप्य यक्षराजो भवेन्नरः ततश्चाश्वयुजे मासि कृत्वैवं नक्तभोजनम्
yakṣalokamanuprāpya yakṣarājo bhavennaraḥ tataścāśvayuje māsi kṛtvaivaṃ naktabhojanam
Having attained the world of the Yakṣas, a man becomes a lord among Yakṣas. Thereafter, in the month of Āśvayuja, by observing the same discipline of eating only at night (naktabhojana), he gains the stated fruit—through the grace of Pati (Śiva), who loosens the pāśa that binds the paśu (the embodied soul).
Suta Goswami (narrating to the sages at Naimisharanya)
It links bodily discipline (naktabhojana as a vrata) with a concrete merit (attaining Yakṣa-loka), implying that regulated living supports purity and steadiness required for Śiva-bhakti and Linga-centered worship.
Though Śiva is not named in the line, the verse functions within a Shaiva merit-framework where Pati (Śiva) is the ultimate dispenser of fruits and the one who can relax pāśa (bondage) for the pashu through disciplined devotion.
Naktabhojana—eating only at night—performed as a vrata in Āśvayuja, a tapas-like restraint that supports sense-control and devotional focus aligned with Shaiva observance.
