स्थिरस्थैर्यमुसलं नाम द्विशरीणतैर्नलः । भाला केंद्रस्थितैः सौम्यैः पापैस्सर्प उदाहृतः ॥ १९३ ॥

Son nom est « Sthira-sthairya-musala » ; par la condition des « deux corps », on l’appelle « Nala ». Ô doux ami, lorsque les planètes bénéfiques occupent les maisons angulaires tandis que les maléfiques se tiennent aux positions centrales, on déclare le (yoga/présage) nommé « Sarpa ».

It frames Jyotiṣa (Vedic astrology) as a dharmic tool: recognizing planetary patterns (yogas/omens) helps a seeker act with awareness, restraint, and right timing—supporting steadiness (sthairya) on the path of Moksha Dharma.
Indirectly: by advising discernment through omens/yogas, it encourages devotees to align actions and vows with auspicious conditions, minimizing obstacles and keeping the mind steady for Vishnu-oriented devotion and disciplined practice.
Jyotiṣa Vedāṅga: the verse references kendra (angular houses) and classification of planetary configurations into named yogas/omens (e.g., “Sarpa”), indicating applied astrological diagnostics.
