The explanation of Modeh Ani according to chasidus is that nothing can defile the purity of a Jew's simple gratitude expressed in this prayer.

The pshat explanation as illuminated by chasidus is that the only true life is a connection with Hashem. From the perspective of the four levels of the soul, G-d enhances one's life. From the perspective of yechidah, G-d is one's life.

(Chs. 11-12)
