लयेशे धर्मगेजीवेष्टस्थे क्रूरक्षिते जिताः । लग्नाष्टमेशावष्टस्थौ भाब्दमायुः करौ मतौ ॥ ११५ ॥
layeśe dharmagejīveṣṭasthe krūrakṣite jitāḥ | lagnāṣṭameśāvaṣṭasthau bhābdamāyuḥ karau matau || 115 ||
إذا كان ربّ الانحلال (زحل) في البيت التاسع بيت الدharma، وكان غورو (المشتري) في البيت الثامن، وكان المريخ مغلوباً؛ وإذا كان ربّ الطالع وربّ البيت الثامن كلاهما في البيت الثامن—فعند المعلّمين يُعدّ العمر سنةً واحدة فقط.

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).
