Whispered prayers do. The Arizal says that every month has a certain letter. And every month has a trait that has to be fixed. When the world ceases to exist for them. All the rebbes say samech is completely surrounded.
Nothing can get closer.
There is no world. There is nothing. You are completely surrounded by G-d. When the house stops being infinite. If a house has everything except the Holy of Holies, then it is just a vessel.
