To consult some monks you will get some other dates which we don’t want to change the date with the embassy.
What we could do is to consider later to invites some monks for lunch at our building.
Another easy option is to invite a monk to the building and pray.
He will put some marks on the entrance doors by white powder.
It’s hard to explain in English but I believe you know what traditional Thai people do when inviting monks to a new office/house.
