Jyotiṣa-saṅgraha: Varga-vibhāga, Bala-nirṇaya, Garbha-phala, Āyuḥ-gaṇanā
रवाहृतूदगनेन्ये तु वक्रि च समागमे । उत्तरस्था दीप्तकराश्चेष्टा वीर्ययुता मताः ॥ २९ ॥
ravāhṛtūdaganenye tu vakri ca samāgame | uttarasthā dīptakarāśceṣṭā vīryayutā matāḥ || 29 ||

It frames Jyotiṣa as a dharmic tool: recognizing when cosmic forces are ‘strong’ (vīrya-yuta) helps time actions wisely, aligning human effort with ṛta (cosmic order).
Indirectly: by emphasizing orderly observation of the cosmos, it supports disciplined living and proper timing of vows and worship—practices that steady the mind for devotion, even though the verse itself is technical.
Jyotiṣa Vedāṅga: it describes indicators of graha-bala—retrograde-related dynamism (ceṣṭā) and heightened radiance (dīpta-karāḥ), especially when the planet is in a northward course (uttara-sthāḥ).
