Davening before the Shechinah

Question: In Sefer Rav Chaim Soloveichik ztz"l on the Rambam, he explained the Rambam in Hilchot Tefillah, that there are two required elements to Tefillah:
a) That one must have Kavanah and understanding of the words one is saying.
b) That one must have Kavanah in his heart that he is standing before the Master of the Universe. Reb Chaim explained this according to the Rambam: without the Kavanah of "standing before G-d," one is not considered to have davened.
How can one acquire the ability to fully feel in his heart that he is standing before the Shechinah? What can one do to grow in this "second" essential element of Tefillah?
Answer: There is no patent on how this is accomplished. It must be worked on slowly and in stages. In areas such as these, each person must grow according to his own level. Look in the Mishnah Berurah (98:1) that the Rash said that after he learned the secrets of Kabbalah he davened like a one day old baby. One grows little-by-little.
