The devotee accepts that it is due to his own past misdeeds that the Supreme Personality of Godhead has caused him some small amount of suffering. Thus he offers obeisances to the Lord again and again. Such a devotee is called mukti-pade sa daya-bhak; that is, he is guaranteed his liberation from this material world. As stated in Bhagavad-gita (2.14):

matra-sparsas tu kaunteya
sitosna-sukha-duhkha-dah
agamapayino nityas
tams titiksasva bharata

We should know that material suffering due to the material body will come and go. Therefore we must tolerate the suffering and proceed with discharging our duty as ordained by our spiritual master.
