This is a Hindi phrase that roughly translates to “the guest is equivalent to God.” It is taken from the Hindu scriptures, and it is a way of describing the relationship of a host to their guests. The basic meaning of this scripture is that any guest in the home should be treated as if God was in the home instead of the guest.
It’s meant to make sure that the guest has a good time and wants to come again. If a hotel uses this as their motto, then they had better live up to it, since it is a scripture.
This is the fifth of such mottos from the Hindu scriptures, and they can be found when this one is looked up online.
