Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
तिथयः पक्षरंध्राख्या ह्यतिरूक्षा प्रकीर्तिताः । समुद्र मनुरंध्रांकतत्त्वसंख्यास्तुनाडिकाः ॥ १३८ ॥
tithayaḥ pakṣaraṃdhrākhyā hyatirūkṣā prakīrtitāḥ | samudra manuraṃdhrāṃkatattvasaṃkhyāstunāḍikāḥ || 138 ||
قيل إنّ التِّثيّات بالغةُ اللُّطف والدقّة، ولذلك سُمّيت «رَنْدهرا (الفتحات) لنصف الشهر (pakṣa)». وأمّا النّاديكا (مقادير الزمن) فتُحسَب وفق التسميات العددية الموروثة مثل «سَمُدْرا (المحيط)»، و«مانو»، و«رَنْدهرا»، و«أَنْكا (رقم/خانة)»، و«تَتْتْفا»، وهي ألفاظ تُستعمل للدلالة على الأعداد.

Bhakti practices like Ekadashi, fasts, and festival worship depend on correct tithi reckoning; the verse emphasizes accurate time-knowledge so devotion is offered at the proper sacred moment, strengthening discipline and sincerity in Vishnu-bhakti oriented observances.
Jyotiṣa Vedāṅga: it highlights calendrical computation—tithi/paksha concepts, nāḍikā as a time-unit, and the use of conventional number-words (bhūta-saṅkhyā) such as samudra and manu for encoding numerical values.
