अन्वयः

ते your, पितृव्यः uncle, वरदानात् by the boons, देवदानवान् Devas and Danavas, सहते with stand, कुम्भकर्णस्तु Kumbhakarna also, वीर्येण courage, सुरासुरान् gods and demons, सहते with stand.

M N Dutt

It is only by virtue of the boon he has received, that your uncle can bear the deities and the Dānavas. But Kumbhakarņa cop with the immortals and Asuras by means of his native might. And in the bow equal to Indrajit himself and in power equal to Rāvana, you now in might and energy are the foremost of Räkşasas.

Summary

"Your uncle Ravana is able to withstand the Devas and Danavas by virtue of the boons and Kumbhakarna was able to with stand gods and demons by virtue of his courage."
