तव your, पृष्ठतः behind, गच्छन्त्याः going, मे to me, तत्र there, पथि on the way, विहारशयनेष्विव on a pleasure stroll or in a (luxurious) couch, कश्चित् even a little, परिश्रमः strain, न भविता will not be.

While following you, I will feel no fatigue there on the way as if I am going on a pleasurestroll or in a comfortable couch.
