Jyotiṣa-saṅgraha: Varga-vibhāga, Bala-nirṇaya, Garbha-phala, Āyuḥ-gaṇanā
लयेशे धर्मगेजीवेष्टस्थे क्रूरक्षिते जिताः । लग्नाष्टमेशावष्टस्थौ भाब्दमायुः करौ मतौ ॥ ११५ ॥
layeśe dharmagejīveṣṭasthe krūrakṣite jitāḥ | lagnāṣṭameśāvaṣṭasthau bhābdamāyuḥ karau matau || 115 ||
Apabila penguasa peleraian (Saturn) berada di rumah kesembilan (dharma), Guru (Jupiter) menempati rumah kelapan, dan Marikh ditundukkan; serta apabila penguasa lagna dan penguasa rumah kelapan kedua-duanya berada di rumah kelapan—maka menurut para guru, jangka hayat dianggap hanya setahun sahaja.
Narada (teaching Jyotisha principles in the Narada Purana context)
Vrata: none
Primary Rasa: bhayanaka
Secondary Rasa: shanta
It frames Jyotiṣa as a Vedāṅga tool for discernment—recognizing fragility of embodied life (āyuḥ) so one turns more urgently toward dharma and liberation-oriented practice.
By emphasizing uncertainty and brevity of life under harsh configurations, it indirectly supports bhakti as the safest refuge—prompting remembrance of the Divine and steady dharmic living rather than complacency.
Jyotiṣa (Vedāṅga astrology): it gives a specific longevity-yoga using house placements (9th and 8th) and the conditions of the lagna lord and 8th lord, yielding an assessment of very short lifespan (about one year).
