Srimad Bhagavatam Canto 10, Chapter 10, Text 26

SB 10.10.26

ity antarenarjunayoh
krsnas tu yamayor yayau
atma-nirvesa-matrena
tiryag-gatam ulukhalam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Having thus spoken, Krsna soon entered between the two arjuna trees, and thus the big mortar to which He was bound turned crosswise and stuck between them.
