Śrāddha-utpatti and Nivāpa–Agni Precedence (श्राद्धोत्पत्तिः—निवापेऽग्निपूर्वकत्वम्)
श्राद्ध यः कृत्तिकायोगे कुर्वीत सततं नर: । अग्नीनाधाय सापत्यो यजेत विगतज्वर:
śrāddhaṃ yaḥ kṛttikāyoge kurvīta satataṃ naraḥ | agnīn ādhāya sāpatyo yajeta vigatajvaraḥ ||
கிருத்திகா-யோகத்தில் எப்போதும் அக்னியை நிறுவி, மகனுடன் சேர்ந்து ஸ்ராத்தம் (பித்ருயஜனம்) செய்பவன், காய்ச்சலும் மனக்கவலையும் அற்றவனாகிறான்.
भीष्म उवाच
Regular performance of śrāddha and pitṛ-yajña at an auspicious time (Kṛttikā-yoga), supported by proper Vedic household practice (establishing sacred fires) and continuity of lineage (with one’s son), is presented as dharmic conduct that yields freedom from illness-like affliction and mental agitation.
In Bhīṣma’s instruction on duties and religious observances, he describes a specific recommended practice—performing śrāddha during Kṛttikā-yoga after installing the sacred fires—and states the beneficial result: the practitioner becomes vigatajvara, free from fever/distress.
