श्राद्ध यः कृत्तिकायोगे कुर्वीत सततं नर: । अग्नीनाधाय सापत्यो यजेत विगतज्वर:,जो मनुष्य सदा कृत्तिका नक्षत्रके योगमें अग्निकी स्थापना करके पुत्रसहित श्राद्ध या पितरोंका यजन करता है, वह रोग और चिन्तासे रहित हो जाता है
śrāddhaṃ yaḥ kṛttikāyoge kurvīta satataṃ naraḥ | agnīn ādhāya sāpatyo yajeta vigatajvaraḥ ||
Bhīṣma said: A man who regularly performs the śrāddha rite when the asterism Kṛttikā is in conjunction, and who—having established the sacred fires—offers worship to the ancestral powers together with his son, becomes free from feverish affliction and inner distress.
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.
