SB 7.3.8
tasyayam kila sankalpas
carato duscaram tapah
sruyatam kim na viditas
tavathapi niveditam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Hiranyakasipu has undertaken a most severe type of austerity. Although his plan is not unknown to you, kindly listen as we submit his intentions.
