The coach and 11 of the 12 boys kneeled and pressed their hands in together prayer to the sound of chanting monks.
The ceremony, which is meant to extend one's life and protect it from dangers, was held at the temple that sits on the northern Thai border overlooking Myanmar.
On Wednesday, the boys and their coach sat down for their first press conference to talk about their ordeal.
"We want to reduce public curiosity", government spokesman Sansern Kaewkamnerd told Reuters on Tuesday. "So we dug holes to find a way to escape and stopped when we were exhausted". And it turned out to be true.
While waiting to be freed, the boys survived on just cave water and tried not to think about their favorite food in order to survive.
"This is the happiest day of my life", she said. "When we found out, everyone was sad".
"(The boys) felt like they were the reason he had to die and his family had to suffer".
The Wild Boars entered the cave on June 23 for what was meant to be a relaxing excursion after soccer practice. But a rainy season downpour flooded the tunnels, trapping them. But in turning back, he discovered the way was not at all clear, and he swam ahead to scout the route, attaching a rope to himself so the boys could pull him back if necessary.
The boys put on a quick demonstration of their ball-handling skills in a special miniature soccer field set up in the hall where they are meeting the media on Wednesday. "We have to find another way".
Their coach quickly told everyone to be quiet. "I really thought it was an overnight thing".
"After they came out of the water, I was really surprised that they (divers) were from the United Kingdom and I didn't know what to say. Be calm and not shocked".

The boys in the team were aged between 11 and 16, while their coach was 25. "I have more patience, endurance, tolerance", he said.
"This experience has taught me that living carelessly has consequences - good and bad", Adul added.
