यत् which, कष्टम् calamity, सः कालः that time, मा भूत् shall not come, माम् to me, शङ्कितुम् to suspect, नार्हसि you should not, मे my, ज्येष्ठः eldest, भ्राता brother, सः राघवः that Rama, पितृसमः is equal to my father, मतः हि he has been held in high esteem.

That calmitous time will never come (again). You should not suspect me. I look upon Rama, my eldest brother, as my father.
