All the monks within the agreed monastic boundary (SIMA) must be present and sitting within arms length of each other. Then two senior monks make a formal announcement to the gathering that the candidate has requested ordination and has been found suitable to become a monk. They continue by proposing three times that he be admitted as a monk. Should any monk in the gathering object to the ordination during these three proposals then the ordination is stopped and the candidate fails to be a monk. If no monk objects, at the end of the third proposal the candidate becomes a monk.
The time has to be noted because the new monk's seniority will be counted from that time. Another monk ordained even a few seconds before him will sit ahead on the line.
