Adoration is one of the most cherished traditions of the Church, developed organically over centuries by countless numbers of martyrs, saints and ordinary people who would regularly empty themselves in the real presence of Jesus as part of their commitment to lives of 'unceasing prayer' (which is in Scripture).   The  Adoration hour is one of the more recent developments that take into account the time constraints of modern living, but by one count, there are nearly 200 Perpetual Adoration chapels in the US.
