अन्वयः

अस्त्रेण by Astra, मुक्तः was released, हनुमान् Hanuman, तैः those, रक्षोभिः by the ogres, कृष्यमाणः dragged, बन्धै: was tied, निपीडितः hurting him, आत्मानम् himself, न अवबुध्यत he did not know

M N Dutt

On being released from the weapon, Hanumān did not betray any signs of his liberation, albeit he was pulled by the Rākşasas and pained by the bonds they had bound him with. And the monkey, Hanumān, was pulled by those cruel Rākṣasas having fatal boxes, in the direction of the lord of Rākşasas.

Summary

Though binding and dragging by the ogres had hurt Hanuman, he on his part did not know that he had been released from Brahmastra.
