This class explores the ויפח, the allusion to Hashem creating the נשמה by blowing.
The idea is explained in the topic of גבורה; which means two things:
1) It takes גבורה to unify opposites; in this case, a נשמה and a physical body.
2) Only while in the body does the true גבורה of the נשמה show itself.
The three aspects of speech vis-a-vis creation:
1) separate from the source
2) limited and moderated air flow
3) divided words
Imagine speaking words while exhaling all the air from your lungs, this is the משל of ויפח.
