'As one might lead a person with his eyes covered away from the Gandhâras, and leave him ​then in a place where there are no human beings; and as that person would turn towards the east, or the north, or the west, and shout, "I have been brought here with my eyes covered, I have been left here with my eyes covered,"

'हे सौम्य, जैसे कोई पुरुष को गन्धार देश से (आँखें बाँधकर) लाए और उसे जन-शून्य प्रदेश में छोड़ दे — वहाँ वह पूर्व, उत्तर, दक्षिण या पश्चिम की ओर मुख करके चिल्लाएगा — "मुझे आँखें बाँधकर लाया गया, आँखें बाँधकर छोड़ा गया।"'
