In this first posy, the poet says if people want to live, the fate must respond positively. That is the firm will to require a decent life is the only way to aquire it, because the fate is subjected to this requirement.

In the second posy, the poet emphasizes that It is essential for night to disappear and for restriction to broke inevitably.
Night stands for domination and colonization, and restriction stands for slavery and occupation.

Third posy:
Who is not embraced by the longing of life is evaporated in its atmosphere and disappeared. That is who does not cling to life has no place in it.
