पूर्वविद्धं प्रकुर्वाणो नरकायोपद्यते । कृष्णपक्षे पूर्वविद्धां सत्पमीं च चतुर्दशीम् ॥ ६ ॥
pūrvaviddhaṃ prakurvāṇo narakāyopadyate | kṛṣṇapakṣe pūrvaviddhāṃ satpamīṃ ca caturdaśīm || 6 ||
پُوروِدّھا تِتھی میں عمل کرنے والا نرک کا مستحق ہوتا ہے۔ لیکن کرشن پکش میں سپتمی اور چتُردشی کو پُوروِدّھا ہی مان کر ان کا انुष्ठان کرنا چاہیے۔

It stresses that correct timing (tithi-nirṇaya) is part of Dharma; performing a vow on the wrong tithi is treated as a serious ritual fault with harmful karmic consequences.
Bhakti in the Purāṇic tradition is expressed through disciplined observances; the verse teaches that devotion should be aligned with śāstric timing rather than personal convenience.
It highlights Jyotiṣa/Vedāṅga-based pañcāṅga application—deciding whether a tithi is to be taken as pūrvaviddhā (earlier contact) for specific lunar days in the kṛṣṇa-pakṣa.
