This literally is a request to enter into a relationship with them. There is a whole separate vocabulary reserved for monks and royalty. New Christian believers often struggle with knowing just what language to use when they pray to God. Besides the language frustrations, one soon learns that truth is situational. It is a far greater sin to end a relationship than to lie.
Truth is what continues a relationship.
Even though Khmer put such a strong emphasis on relationships, relationships have been extremely damaged over the years. The beautiful Khmer people have lived through the horrors of genocide and near continuous warfare for a quarter century. Everyone lost loved ones since over a fourth of the population died. Today, Cambodia is a deeply wounded nation and most Cambodians find it very difficult to trust. The irony in Khmer culture is that relationships are extremely important yet extremely difficult to develop.
