Valmiki Ramayana Yuddha Kanda Sarga 45 Shloka 21

क्रूरेण by the cruel, कामरूपिणा capable of acquiring desired form, रक्षसा Rakshasa, निहतौ wounded, तौ both, प्रस्रवणौ flowed, जलम् इव like water, तीव्रम् copiously, असृक् vital breaths, सुस्रुवतुः brought forth.

Wounded by the cruel Rakshasas capable of changing form at their will, blood flowed from their body copiously like water from spring bringing out their vital life breaths.
