SB 11.7.13
sri-suka uvaca
ity adisto bhagavata
maha-bhagavato nrpa
uddhavah pranipatyaha
tattvam jijñasur acyutam
Translation:
Sri Sukadeva Gosvami said: O King, the Supreme Personality of Godhead, Lord Krsna, thus instructed His pure devotee Uddhava, who was eager to receive knowledge from the Lord. Uddhava then offered obeisances to the Lord and spoke as follows.
Purport:
Uddhava is described here as tattvam jijñasuh, or desiring to know the truth. It is clear from previous verses that Sri Uddhava is a pure devotee of Lord Krsna and that he considers devotional service to Lord Krsna to be the perfection of life. Thus the words tattvam jijñasuh indicate that since Lord Krsna is about to leave the earth, Uddhava is most anxious to deepen his understanding of the Lord so that he may further advance in loving service at the Lord’s lotus feet. Unlike an ordinary philosopher or scholar, a pure devotee is not eager to acquire knowledge for personal gratification.
