Blended reading (Sanskrit + English inline)
bālya-līlāya āge prabhura uttāna śayana pitā-mātāya dekhāila cihna caraṇa
In His first childhood pastimes the Lord turned upside down while lying on His bed, and thus He showed His parents the marks of His lotus feet.
Purport
The word uttāna is also used to mean “lying down on the bed face upwards” or “lying down flat on the bed.” In some readings the word is utthāna, which means “standing up.” In His childhood pastimes the Lord tried to catch the wall and stand up, but as an ordinary child falls down, so the Lord also fell down and again took to lying on His bed.
— A.C. Bhaktivedanta Swami Prabhupāda
