iti bhagavatah prstah
ksattra vartam priyasrayam
prativaktum na cotseha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: When the great devotee Uddhava was asked by Vidura to speak on the messages of the dearest [Lord Krsna], Uddhava was unable to answer immediately due to excessive anxiety at the remembrance of the Lord.
