Śrīmad-Bhāgavatam · Text 11.7.74
Who is speaking and story frame
य: प्राप्य मानुषं लोकं मुक्तिद्वारमपावृतम् ।
गृहेषु खगवत् सक्तस्तमारूढच्युतं विदु: ॥ ७४ ॥
yaḥ prāpya mānuṣaṁ lokaṁ
mukti-dvāram apāvṛtam
gṛheṣu khaga-vat saktas
tam ārūḍha-cyutaṁ viduḥ
The doors of liberation are opened wide to one who has achieved human life. But if a human being simply devotes himself to family life like the foolish bird in this story, then he is to be considered as one who has climbed to a high place only to trip and fall down.
