तव your, शत्रवः enemies, हीनवीर्याः deprived of valour, निशाचराः demons, त्वाम् you, बलीयसा by a strong person, उपरुद्धम् obstructed, विनश्यन्तम् being destroyed, इच्छन्ति they like, सुव्यक्तम् it is very clear,

This is clear that your enemy demons are now powerless. Hence they want you to be engaged with a stronger power and be destroyed.
