CHĀNDOGYA UPANISHAD · 6.14.2

तस्य यथाभिनहनं प्रमुच्य प्रब्रूयाद् एतां दिशं गन्धारा एतां दिशं व्रजेति ।
स ग्रामाद् ग्रामं पृच्छन् पण्डितो मेधावी गन्धारान् एवोपसंपद्येत ।
एवम् एवेहाचार्यवान् पुरुषो वेद ।
तस्य तावद् एव चिरं यावन् न विमोक्ष्ये ऽथ संपत्स्य इति ॥

tasya yathābhinahanaṃ pramucya prabrūyād etāṃ diśaṃ gandhārā etāṃ diśaṃ vrajeti ।
sa grāmād grāmaṃ pṛcchan paṇḍito medhāvī gandhārān evopasaṃpadyeta ।
evam evehācāryavān puruṣo veda ।
tasya tāvad eva ciraṃ yāvan na vimokṣye ’tha saṃpatsya iti ॥

'And as thereupon some one might loose his bandage and say to him, "Go in that direction, it is Gandhâra, go in that direction;" and as thereupon, having been informed and being able to judge for himself, he would by asking his way from village to village arrive at last at Gandhâra,--in exactly the same manner does a man, who meets with a teacher to inform him, obtain the true knowledge. For him there is only delay so long as he is not delivered (from the body); then he will be perfect.
