SB 1.7.17
iti priyam valgu-vicitra-jalpaih
sa santvayitvacyuta-mitra-sutah
anvadravad damsita ugra-dhanva
kapi-dhvajo guru-putram rathena
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Arjuna, who is guided by the infallible Lord as friend and driver, thus satisfied the dear lady by such statements. Then he dressed in armor and armed himself with furious weapons, and getting into his chariot, he set out to follow Asvatthama, the son of his martial teacher.
