parama santoṣa prabhura vanya-bhojane
mahā-sukha pāna, ye dina rahena nirjane
Word for word: 
parama — very much; santoṣa — satisfaction; prabhura — of the Lord; vanya-bhojane — in eating vegetables collected from the forest; mahā-sukha pāna — gets great happiness; ye dina — on which day; rahena — stays; nirjane — in a solitary place.
Translation: 
The Lord was always very happy to eat these forest vegetables, and He was even happier when He had an opportunity to stay in a solitary place.
