दशशैवव्रतप्रश्नः — Inquiry into the Ten Principal Śaiva Vratas
प्रत्यष्टम्यां प्रयत्नेन कर्तव्यं नक्तभोजनम् । कालाष्टम्यां विशेषेण हरे त्याज्यं हि भोजनम्
pratyaṣṭamyāṃ prayatnena kartavyaṃ naktabhojanam | kālāṣṭamyāṃ viśeṣeṇa hare tyājyaṃ hi bhojanam
في اليوم السابق للأَشْتَمي (Aṣṭamī) ينبغي أن يُلتزم باجتهادٍ بنذر «نكتبهوجنا» أي الأكل ليلًا فقط. أمّا في «كالا أَشْتَمي» (Kālāṣṭamī) على وجه الخصوص، يا هارا، فيجب ترك الطعام تركًا تامًّا.
Suta Goswami
Tattva Level: pashu
Shiva Form: Mahākāla
Jyotirlinga: Mahākāleśvara
Sthala Purana: Mahākāla is revered as the Lord of Time who grants protection from untimely death and fear; Kālāṣṭamī observance aligns with propitiating Śiva as Kāla/mahākāla through fasting and restraint.
Significance: Austerity on Kālāṣṭamī is held to pacify time-bound afflictions and purify pāśa; pilgrimage to Mahākāleśvara is sought for fearlessness and spiritual steadiness.
Shakti Form: Kālī
Role: destructive
Cosmic Event: Kālāṣṭamī (time-associated aṣṭamī observance; liminal ‘kāla’ emphasis)
It teaches tapas (austerity) through regulated eating: restraint on the eve of Aṣṭamī and complete fasting on Kālāṣṭamī, offered as a devotional discipline to Hara that purifies the mind for Shiva-bhakti.
Food-restraint is presented as an offering of self-control to Saguna Shiva (Hara) during vrata-days; such discipline supports focused Linga-puja by reducing tamas and strengthening devotional steadiness.
Observe naktabhojana on the prior day and upavasa (fasting) on Kālāṣṭamī, and pair it with Shiva-japa (e.g., Om Namaḥ Śivāya) and simple Linga worship with a purified, restrained mind.
