PrU 1.2
तान् ह स ऋषिर् उवाच । भूय एव तपसा ब्रह्मचर्येण श्रद्धया संवत्सरं संवत्स्यथ । यथाकामं प्रश्नान् पृच्छत । यदि विज्ञास्यामः सर्वं ह वो वक्ष्याम इति
tān ha sa ṛṣir uvāca | bhūya eva tapasā brahmacaryeṇa śraddhayā saṃvatsaraṃ saṃvatsyatha | yathākāmaṃ praśnān pṛcchata | yadi vijñāsyāmaḥ sarvaṃ ha vo vakṣyāma iti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
That Rishi said to them: "Stay here a year longer, with penance, abstinence, and faith; then you may ask questions according to your pleasure, and if we know them, we shall tell you all."
