Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: O King, after hearing all these most virtuous topics from the sage Maitreya, Vidura inquired further on the topics of the Supreme Personality of Godhead, which he adored to hear.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word adrtah is significant because it indicates that Vidura had a natural inclination for hearing the transcendental message of the Supreme Personality of Godhead, and he was never fully satisfied though continuing to hear those topics. He wanted to hear more and more so that he could be more and more blessed by the transcendental message.
