चंद्रागांतरगैः खेटैः सूतिकाः समुदाहृताः । चक्राद्धि बहिरंतश्च दृश्यादृश्योपरेऽन्यथा ॥ ९० ॥
caṃdrāgāṃtaragaiḥ kheṭaiḥ sūtikāḥ samudāhṛtāḥ | cakrāddhi bahiraṃtaśca dṛśyādṛśyopare'nyathā || 90 ||
चन्द्र की गति-सीमा के भीतर जो ग्रह-लक्षण प्रकट हों, वे ‘सूतिका’ कहलाते हैं। वे चक्र के बाहर या भीतर भी हो सकते हैं; और ऊर्ध्व लोकों में वे कहीं दृश्य, कहीं अदृश्य—अन्य प्रकार से भी प्रकट होते हैं।

It frames celestial phenomena under dharmic discernment: not every sign is obvious to the senses, so one should rely on śāstra-guided understanding rather than fear or superstition.
By implying that cosmic signs fluctuate as visible/invisible, it nudges the seeker toward steadiness—placing trust in Bhagavān and dharma rather than being mentally shaken by omens.
Jyotiṣa (Vedāṅga astrology): it classifies “sūtikā” as planetary/astral indications associated with the Moon’s course and notes observational categories (inside/outside a celestial circle; visible/invisible).
