Morning Blessings: The Purity of the Soul
“My Lord, the Soul that You placed in me, she is pure.” This can be understood according to the Nefesh Hachaim (First Gate, Chapter 18) who explains that a person’s soul is not damaged at all in this world. The souls root is in the highest worlds and is guarded and safe. A person’s actions cannot reach into those worlds.
When a person sins, he blocks the light that can shine from his soul’s root into him.
This is why we recall every morning, that our soul is pure. We remind ourselves of the power and purity of our souls and reconnect to the source in order to receive all her light. (Shirat David pg. 39)
