Jyotiṣa-saṅgraha: Varga-vibhāga, Bala-nirṇaya, Garbha-phala, Āyuḥ-gaṇanā
चरे सन्मध्यदुष्टाभ्यामंगभंगे विपर्ययात् । स्थिरे नेष्टष्टमध्या च होरायास्त्र्यं शकैः फलम् ॥ १४९ ॥
care sanmadhyaduṣṭābhyāmaṃgabhaṃge viparyayāt | sthire neṣṭaṣṭamadhyā ca horāyāstryaṃ śakaiḥ phalam || 149 ||
In movable signs, the results are declared as good, middling, or harmful according to the condition of the horā; but in cases of bodily injury, the indications are to be taken in reverse. In fixed signs, the outcomes are regarded as undesirable—especially when linked with the eighth place and the middle. Thus the Śakas teach the threefold result of the horā.

It frames Jyotiṣa (Vedāṅga astrology) as a disciplined interpretive tool: outcomes are not read mechanically, but by rules (movable vs. fixed signs) and contextual correction (viparyaya in injury), encouraging careful discernment in dharmic decision-making.
Indirectly: it supports a devotee’s dharmic life by teaching how to judge time-signs (horā) prudently; such prudence is meant to aid righteous conduct, within which Viṣṇu-bhakti and mokṣa-oriented living can be pursued without superstition.
Vedāṅga Jyotiṣa—specifically horā-phala (hour/divisional results), interpretation by rāśi-type (movable vs. fixed), the inauspicious role of the eighth place, and the rule of viparyaya (reversal) when reading indications for bodily injury.
