Gṛhastha-nitya-karman: Śauca, Sandhyā-vidhi, Pañca-yajña, and Āśrama-krama
नोपास्ते यो द्विजः संध्यां धूर्तबुद्धिरनापदि । पाषंडः स हि विज्ञेयः सर्वधर्मबहिष्कृतः ॥ ६७ ॥
nopāste yo dvijaḥ saṃdhyāṃ dhūrtabuddhiranāpadi | pāṣaṃḍaḥ sa hi vijñeyaḥ sarvadharmabahiṣkṛtaḥ || 67 ||
ఏ నిజమైన ఆపద లేకుండానే కపటబుద్ధితో సంధ్యోపాసన చేయని ద్విజుడు పాషండుడని తెలుసుకోవాలి; అతడు సమస్త ధర్మాచరణల నుండి బహిష్కృతుడు।

It asserts that Sandhyā worship is a core daily discipline (nitya-karma) for the twice-born; neglecting it without real impediment is treated as a serious fall from Vedic dharma, marking one as outside orthodox conduct.
By insisting on Sandhyā-upāsanā, the text emphasizes that steady daily worship and self-discipline form the ground on which higher devotion matures; bhakti is supported by regular practice rather than negligence and pretense.
It highlights āhnika/nitya-karma procedure—especially Sandhyā-vandana timing and obligation—connected with Śikṣā (mantra recitation discipline) and Kalpa (ritual rule), stressing correct observance when no valid obstacle exists.
