बीजयोन्यविशुद्धस्तु यथा रुद्रं न विन्दति । तथा लाङ्गलमन्त्रोऽपि न तिष्ठति गतायुषि
bījayonyaviśuddhastu yathā rudraṃ na vindati | tathā lāṅgalamantro'pi na tiṣṭhati gatāyuṣi
كما أن من كانت بذرتُه ونَسَبُه غيرَ طاهرين لا ينال رُدرا، كذلك مانترا «لانغالا» لا تبقى نافعةً لمن استُنفِد عمرُه، وقد بلغ نهايةَ حياته الروحية.
Mārkaṇḍeya (continuing)
Tirtha: Revā (Narmadā) tirtha milieu
Type: kshetra
Scene: A contemplative teacher on the riverbank instructs a weary, aged seeker; the mantra’s glow fades around the unprepared, while Rudra’s distant form remains unattained—visualizing conditional efficacy.
Mantra practice is linked with adhikāra (fitness): purity and preparedness condition spiritual attainment and efficacy.
Not explicit in this verse; it continues within the Revā/Narmadā-centered discourse of the chapter.
A caution regarding the Lāṅgala-mantra: it requires proper fitness/purity and does not ‘stand’ (remain effective) under disqualifying conditions.
