प्राप हाचर्यकुलम् । तम् आचर्यो ऽभ्युवाद सत्यकाम ३ इति । भगव इति ह प्रतिशुश्राव
prāpa hācaryakulam | tam ācaryo 'bhyuvāda satyakāma 3 iti | bhagava iti ha pratiśuśrāva
Thus he reached the house of his teacher. The teacher said to him: 'Satyakâma.' He replied: 'Sir.'
Translated by F. Max Müller
ब्रह्मविद् इव वै सोम्य भासि । को नु त्वानुशशासेति । अन्ये मनुष्येभ्य इति ह प्रतिजज्ञे । भगवांस् त्व् एव मे कामे ब्रूयात्
brahmavid iva vai somya bhāsi | ko nu tvānuśaśāseti | anye manuṣyebhya iti ha pratijajñe | bhagavāṃs tv eva me kāme brūyāt
The teacher said: 'Friend, you shine like one who knows Brahman. Who then has taught you?' He replied: 'Not men. But you only, Sir, I wish, should teach me;
Translated by F. Max Müller
श्रुतं ह्य् एव मे भगवद्दृशेभ्य आचार्याद् धैव विद्या विदिता साधिष्ठं प्रापतीति । तस्मै ह एतद् एव उवाच । अत्र ह न किंचन वीयायेति वीयायेति
śrutaṃ hy eva me bhagavaddṛśebhya ācāryād dhaiva vidyā viditā sādhiṣṭhaṃ prāpatīti | tasmai ha etad eva uvāca | atra ha na kiṃcana vīyāyeti vīyāyeti
'For I have heard from men like you, Sir, that only knowledge which is learnt from a teacher (Âkârya), leads to real good.' Then he taught him the same knowledge. Nothing was left out, yea, nothing was left out.
