It can be suggested that the "air (spirit) of Moshiach" is even higher than "the light of Moshiach," because the light of Moshiach indicates the revelation of Moshiach through his actions (such as "he will fight the wars of G-d" until "he is victorious," etc.). However the air of Moshiach indicates the essence (the very life) of Moshiach. That is, [this refers to] the revelation of his existence (from his earlier status as a leader) as the King Moshiach. And after the revelation of his existence (air that is incomparable to the light of Moshiach) begins the revelation that all can see through his activity (light of Moshiach).
Accordingly, it can be understood that the main innovation in the coming of Moshiach is the revelation of his existence ("I found Dovid my servant"), because all the details that follow (his public revelation through his activities to redeem Israel, and everything concerned with the days of Moshiach) come as a consequence of the revelation of his existence, and are included in it.
...In terms of the practical relevance - "Action is the main thing" - is that every Jew needs to increase with additional strength and vigor the concept that "all the days of your life to bring about the days of Moshiach." His entire existence, immediately upon awakening from his sleep, is penetrated with the life of Moshiach (for this is the essence of the existence of every Jew, the Moshiach within him).
