Sandarbhasūkti - part 24
207. Yat karabhasya pṛṣṭhe na māti tat kaṇṭhe nibadhyate
The master fastens an unbearable load around the camel’s neck! Camels are known to bear huge loads. When there is already a humongous load on its back, if something is fastened around its neck, imagine the plight. When one goes through unbearable difficulties, this is used to describe their fate. This can also be applied when something which is unbearable to a strong man is thrust upon a weakling.
