Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 8
Sanskrit:
खगा वीतफलं वृक्षं भुक्त्वा चातिथयो गृहम् ।दग्धं मृगास्तथारण्यं जारा भुक्त्वा रतां स्त्रियम् ॥ ८ ॥
ITRANS:
khagā vīta-phalaṁ vṛkṣaṁbhuktvā cātithayo gṛhamdagdhaṁ mṛgās tathāraṇyaṁjārā bhuktvā ratāṁ striyam
Translation:
Birds abandon a tree when its fruits are gone, guests a house after they have eaten, animals a forest that has burnt down, and a lover the woman he has enjoyed, even though she remains attached to him.
