Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
जीर्णं पतिं यौवनगर्विता यथा त्यजंति नार्यो झषकेतुनार्दिताः । तथा हि वेधं विबुधास्त्यजंति तिथ्यंतरं धर्मविवृद्धये सदा ॥ ४६ ॥
jīrṇaṃ patiṃ yauvanagarvitā yathā tyajaṃti nāryo jhaṣaketunārditāḥ | tathā hi vedhaṃ vibudhāstyajaṃti tithyaṃtaraṃ dharmavivṛddhaye sadā || 46 ||
正如女子自恃青春,被迦摩(旗帜绘鱼者)所激起的欲火所扰而弃老夫;同样,智者恒常舍弃被“遮破”的月日(vedha之tithi),改择他日,以令法(dharma)不断增长。

It teaches that dharma is protected by proper observance: when a tithi is ‘vedha’ (ritually obstructed/unsuitable), the wise shift to a suitable alternate tithi so that the rite produces true merit rather than mere formality.
Bhakti is supported by disciplined practice—devotional vows and worship become most fruitful when performed at the proper sacred time; thus the devotee follows scriptural timing (tithi-śuddhi) to honor the deity correctly.
Jyotiṣa (Vedāṅga astrology) and pañcāṅga-based timekeeping: identifying tithi, recognizing vedha/obstruction, and selecting the correct alternative day for vratas and rituals.
