Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
सपिंड्यांतरलग्नासूनेवं स्यात्कालसाधनम् । विराह्वर्कभुजांशाश्चेदिंद्राल्पाः स्याद् ग्रहो विधोः ॥ १५३ ॥
sapiṃḍyāṃtaralagnāsūnevaṃ syātkālasādhanam | virāhvarkabhujāṃśāścediṃdrālpāḥ syād graho vidhoḥ || 153 ||
આ રીતે પિંડ અને લગ્ન વચ્ચેના અંતર (અંતર)ના નિયમથી કાળ-સાધન થાય છે. અને જો વિરાહ તથા અર્ક-ભુજાંશ વગેરે ગણિત અંશો ‘ઇન્દ્ર’ એકકથી પણ ઓછા હોય, તો વિધુ (ચંદ્ર)નો ગ્રહ (ગ્રાહક પ્રભાવ) કાર્યકર માનવો।

It emphasizes that Dharma and Moksha-oriented practices should be performed with proper kāla (time), because correct timing (kāla-sādhana) supports purity, steadiness of mind, and the intended fruit of ritual or observance.
While the verse is technical (Jyotiṣa), it indirectly supports Bhakti by guiding devotees to perform Vishnu-oriented rites and vows at properly determined times, reducing obstacles (graha-doṣa) and aiding focused worship.
Vedāṅga Jyotiṣa: determining time via lagna-based intervals and arc-measures, and applying a conditional rule for when very small computed values indicate a Moon-related graha/affliction.
