अन्वयः

अयोध्यायाम् in Ayodhya, गुरुमध्ये in the presence of elders, महात्मना by the magnanimous, पित्रा father, दशरथेन by Dasaratha, अहम् I, अनुशिष्ट: अस्मि have been ordered, तद्वच: his words, नावज्ञेयं हि cannot be disobeyed(turned down).

M N Dutt

In accordance with the desire of my sire, and in order to glorify it, I ought fearlessly to do even as Kusika's son says. And having been desired to that end while at Ayodhyā by that high-souled one, my father Dasaratha, in the midst of the spiritual guides, I ought not to pass by your words.

Summary

In Ayodhya in the presence of elders and spiritual masters (of Dasaratha's court), I have been ordered by my magnanimous father to act according to your instructions and his words cannot be disobeyed.
