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).

The essential point in the life of every Jew
and that of the Jewish people as a whole throughout all the generations has been: "All the days of your life to bring about the days of Moshiach."
This requires extra emphasis in this generation and in our times, as mentioned frequently of late, that all aspects have been completed and we need only greet our righteous Moshiach in actuality.
..."All the days of your life" means every moment of a person's life, day or night, awake or asleep, for he is still alive then through his breathing ("All that breathes praises G-d," and "with each and every breath a person breathes..."), which is necessary every moment (unlike eating and drinking). And "all the days of your life to bring about the days of Moshiach" means that his life (every instant of it) is bringing the days of Moshiach. That is, a Jew does not limit himself only to those times when he thinks or speaks or does something to bring Moshiach. Rather the essence of his life ("your life") is to bring the days of Moshiach.
...In more detail: The concept of "All the days of your life to bring about the days of Moshiach" expresses that immediately when the essence of the soul awakens (thus revealing the essence, and only the essence, of its existence), it feels in the very air it breathes the concept of Moshiach, the air of Moshiach, or in the words of our Sages of blessed memory, "the spirit of King Moshiach."
