etadgośakṛtaḥ putra māhātmyaṃ te'nuvarṇitam |
māhātmyaṃ ca gavāṃ bhūyaḥ śrūyatāṃ gadato mama || 26 ||

"Bhishma continued, 'Having, O Bharata, made this compact with the kine, Sri, there and then, in the very sight of those kine, rendered herself invisible. I have thus told thee, O son, the glory of the dung of kine, I shall once again discourse to thee on the glory of kine. Do thou listen to me."
