Verses 16-17-18

Though happiness and sorrow
Do not stick to us,
In a moment of excitement
We see ourselves as happy or sad
Giving rise to objects of seeing.
These impressions conjure up
The seer, like the reflection
Bringing to life the (separate) person.
This three-way split impression of the seen,
The seer and the seeing
We establish by flowing with
Impressions.

In treating me and the message to me as separate from you, you are also treating yourself as somebody separate from this flow of energy. What is this excitement about?
