eṣā hyasya parā prītirhṛdi saṃparivartate kadā nāma sutaṃ drakṣyāmyabhiṣiktamahaṃ priyam|
The thought of seeing his dear son coronated repeatedly surfaced his mind so great was his affection (for Rama).
— M.N. Dutt (1891)
Dasharatha's mind keeps returning to the thought of Rama's coronation. The repetition mirrors his excitement — he cannot stop thinking about it. The verse captures the joy of a father who believes he is about to see his son's greatest moment. The dramatic irony is already at work.
