अन्वयः

दैवतम् divine power, कालेन in course of time, किंचित् even a little, बलवत्तरम् more strong, न not, नूनम् surely, यत्र where, सः दाशरथि: that Dasaratha's son, रामः Rama, भूमावेव on the ground itself, शयीत had to sleep.

M N Dutt

Verily, no destiny is superior to Time, since Dasaratha's son, Rāma himself, had to repose on the earth, and the beauteous beloved daughter of Videha's king, and the daughter-in-law of Dasaratha, had to lie down on the ground.

Summary

Dasaratha's son, Rama had to rest on the ground would admittedly mean that no divine power is mightier than Time (Destiny).
