Valmiki Ramayana Yuddha Kanda Sarga 85 Shloka 26

अद्य now, मत्कार्मुकोन्मुक्ताः released from my bow, शराः arrows, रावणिम् son of Ravana's, निर्भिद्य piercing, हंसाः swans, पुष्करिणीमिव descend into lotus pond, लङ्काम् Lanka, अभिपतिष्यन्ति will drop

Now the arrows released from my bow will drop in Lanka, just as swans descend into lotus pond and pierce into Ravana's son.
