SB 3.20.47
dehena vai bhogavata
sayano bahu-cintaya
sarge ’nupacite krodhad
utsasarja ha tad vapuh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Once Brahma lay down with his body stretched at full length. He was very concerned that the work of creation had not proceeded apace, and in a sullen mood he gave up that body too.
