In plain words
The poet says: Before the long sleep of the eyes comes, as urine trickles down at the lap [in fear of Yama's messengers] and the gruel poured into your mouth comes back, runs out at the corners and chokes your throat: if you can praise him, calling him Hṛṣīkēśa, then in Yama's world dogs will not seize you by the thighs, his men will not pierce you with spears, and you will not lose even your clothes on the road between.
