In plain words
The poet, telling of Rāma of Tillai Citrakūṭam: The young hero who loosed a single mighty arrow that tore open the breast of Tāṭakā, who came to oppose him, so that the blood streamed out, who guarded the sacrifice of the sage [Viśvāmitra] who holds the mantras of the Vedas, and took the lives of the mighty rākṣasas [Subāhu and Mārīca]: know that he is the Lord himself, seated on a lovely jewelled throne, praised by the three thousand brahmins, in Tiruccitrakūṭam in the town of Tillai, among rich, cool groves where flowers smile amid red young shoots.
