SB 3.12.51
aho adbhutam etan me
vyaprtasyapi nityada
na hy edhante praja nunam
daivam atra vighatakam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Brahma thought to himself: Alas, it is wonderful that in spite of my being scattered all over, there is still insufficient population throughout the universe. There is no other cause for this misfortune but destiny.
