Lakshmaṇ the brave, his brother’s peer In princely virtues, followed near, Sore troubled, but resolved to show No token of his secret woe. Thus to the palace Ráma went Where all were gay with hope and joy; But well he knew the dire event That hope would mar, that bliss destroy.

In plain words: His brother Lakshmana follows him, deeply upset but hiding it. Rama enters the palace, where everyone is happy and hopeful, knowing his news will destroy their joy.
