G. Contemplation of how all is naught before G-d arouses love of G-d:^[1]

How does one achieve the arousal of a feeling of love, Viahavta, in Shema? This is through contemplating the message behind the first verse of the Shema. In this verse we unify G-d and contemplate his sovereignty over all the directions of the universe. The deeper message behind this verse is the idea that G-d fills entire universe with His glory and that there is no place devoid of His essence as is known that in truth the essence of G-dliness fills the entire earth. Accordingly, it is found that everything is nullified to His existence similar to the nullification of a ray of the sun within the sun itself. Now, when a person contemplates this message during Pesukei Dezimra and Shema he will be aroused with a passionate desire to cleave to the one G-d that is found in the very place that he is in.
