In Rabbi Donin's book, To Pray As A Jew, he says that reading a prayer book to find out what it says, or to relish its beauty of poetry, does not qualify as prayer. He says that to transform reading into prayer, there must be at least a sense of standing in the presence of G-d and the intent to fulfill one of His commandments. He called this "intent" kavanah.
Rabbi Donin states in his book that there are ascending levels of kavanah, each one a greater challenge to the worshiper. I want to know what those different levels are.
