As Thailand celebrated the 60-year reign of King Bhumibol Adulyadej last year, it was his only son who spoke on behalf of the royal family.
'I and your loyal family vow that we are determined to be honest and loyal, in honour and harmony, refraining from any act that might make your majesty unhappy,' Crown Prince Maha Vajiralongkorn said.
Solemn as they were, the words were also soothing to many ordinary Thais, who struggle to imagine life without the king. The constitutional monarch is revered almost as a god, the one constant guiding the country above a sometimes volatile and venal political arena.
For some, the crown prince's words continue to resonate amid fresh uncertainties about the future. Thailand last week marked the king's 80th birthday with another outpouring of warmth and respect - celebrations tinged with concern over his health after a recent spell in hospital for symptoms similar to a stroke.
Next week Thailand goes to the polls for its first election since last year's military coup to oust prime minister Thaksin Shinawatra. With Thaksin-allied groups competing and a shaky coalition expected, months of potential uncertainty lie ahead.
Once again, some fear the king will be called on to exert his moral authority to avert crisis.
