Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 13


श्रीशुक उवाचइत्यादिष्टो भगवता महाभागवतो नृप ।उद्धव: प्रणिपत्याह तत्त्वंजिज्ञासुरच्युतम् ॥ १३ ॥


śrī-śuka uvācaity ādiṣṭo bhagavatāmahā-bhāgavato nṛpauddhavaḥ praṇipatyāhatattvaṁ jijñāsur acyutam


Śrī Śukadeva Gosvāmi said: O King, the Supreme Personality of Godhead, Lord Kṛṣṇa, 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.


Uddhava is described here as tattvaṁ jijñāsuḥ, or desiring to know the truth. It is clear from previous verses that Śrī Uddhava is a pure devotee of Lord Kṛṣṇa and that he considers devotional service to Lord Kṛṣṇa to be the perfection of life. Thus the words tattvaṁ jijñāsuḥ indicate that since Lord Kṛṣṇa 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.
