SB 10.45.9
tat ksantum arhathas tata
matar nau para-tantrayoh
akurvator vam susrusam
klistayor durhrda bhrsam
Translation:
Dear Father and Mother, please forgive Us for not serving you. We are not independent and have been greatly frustrated by cruel Kamsa.
Purport:
According to Sanskrit grammar, the words para-tantrayoh and klistayoh may also refer to Vasudeva and Devaki. Actually, Vasudeva and Devaki were under the control of Providence and were disturbed by the activities of Kamsa, whereas Sri Krsna is always the absolute Personality of Godhead.
