In the prayer of "Nishmas Kol Chai" we say: "If our mouths were filled with song like the sea, and our tongues with melody like the multitude of its waves, and our lips with praise like the breadth of the sky… we could still not praise you sufficiently"
But on the other hand we say: "Therefore the limbs which you set within us… they shall all thank, bless…"- how can it make sense?

In this work we can understand an answer to this question: Man's ability to thank Gd for all the benefits we have given is by man fulfilling Gd's will with his body, spirit and soul – that is, by keeping the Torah and the Mitzvos – which is reflected in this work Through Torah study and prayer.
