शनैश्चरदिने स्पृष्ट्वा दीर्घायुष्यं लभेन्नरः शनैश्चरदिने ऽश्वत्थं पाणिभ्यां संस्पृशेत्सुधीः
śanaiścaradine spṛṣṭvā dīrghāyuṣyaṃ labhennaraḥ śanaiścaradine 'śvatthaṃ pāṇibhyāṃ saṃspṛśetsudhīḥ
On the day of Śanaiścara (Saturday), by performing the prescribed auspicious touch, a person attains long life. Therefore, on Saturday the wise should touch the aśvattha (sacred fig) tree with both hands.
Suta Goswami (narrating to the sages of Naimisharanya)
It frames longevity (dīrghāyuṣya) as a fruit of disciplined vrata-practice aligned with Shiva’s dharma; such niyamas support steadiness for Linga-puja and inner purification of the pashu (soul).
Shiva-tattva is implied as the giver of auspicious results through dharmic observance: by aligning conduct with sacred time (Saturday) and sacred supports (aśvattha), the bound soul moves toward Shiva’s anugraha (grace) that loosens pāśa (bondage).
A simple vrata-aṅga (auxiliary observance): on Saturday, reverently touching the aśvattha with both hands as an auspicious act for āyuḥ (life-force/longevity), supporting steadiness for further puja and sādhanā.
