Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
स्वातित्रये पश्चिमायां तस्यां शुक्रस्तथाविधः । विपरीते त्वनावृष्टिर्वृष्टिकृद्बुधसंयुतः ॥ ६९ ॥
svātitraye paścimāyāṃ tasyāṃ śukrastathāvidhaḥ | viparīte tvanāvṛṣṭirvṛṣṭikṛdbudhasaṃyutaḥ || 69 ||
During the threefold period of Svātī, if it lies in the western quarter, then Śukra (Venus) too is regarded as being in that same condition. If it is the reverse, there is lack of rain (anāvṛṣṭi); but when joined with Budha (Mercury), it becomes a causer of rainfall.
Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames natural events like rain within dharmic order, showing that careful observation (Jyotiṣa-based omens) supports righteous living—protecting society through timely planning and restraint during scarcity.
Indirectly: by encouraging disciplined, attentive living aligned with cosmic rhythms, it supports a sattvic life where duties are performed steadily—an essential foundation for sustained Viṣṇu-bhakti and worship without negligence.
Vedāṅga Jyotiṣa: using nakṣatra periods (Svātī), directional placement, and planetary conjunctions (Śukra with Budha) as technical indicators to judge rainfall versus drought.
