And again the wise boy, with his mind solely devoted to him and controlling his mind and speech, sang the glory of that excellent Purusha who is without beginning: Prahlāda said,—"Salutation unto thee who art the true wisdom, who art subtile and substantial, mutable and immutable, perceptible and unperceptible, who art with form and without it, indescribable and describable.

In plain words: With his mind and words fully focused, the wise boy Prahlada began praising Vishnu, the Purusha (Supreme Being) who has no beginning. He bows to God as true wisdom, and says God is both things we can see and things we cannot, both with form and beyond form, both beyond words and described in words.
