Verse 2

When people see some things as beautiful,
other things become ugly.
When people see some things as good,
other things become bad.

Being and non-being create each other.
Difficult and easy support each other.
Long and short define each other.
High and low depend on each other.
Before and after follow each other.

Therefore the Master
acts without doing anything
and teaches without saying anything.
Things arise and she lets them come;
things disappear and she lets them go.
She has but doesn't possess,
acts but doesn't expect.
When her work is done, she forgets it.
That is why it lasts forever.

Interpretation(s):
This verse begins with the notion of duality and how the distinctions that we create can increase our attachment to to material things and possibly even cloud our perspective.  So, the final paragraph discusses how the Master flows in harmony with the Universe and avoids false, transient distinctions.

The Master's actions are free from expectations.  That is my favorite part of this verse.  That is echoed many times in the Bhagavad Gita to act while renouncing the fruits of your actions.  You act for the sake of doing your best at perfecting the act itself towards its purpose without worrying about what you may get out of it.  For example, I practice the art of Jiu Jitsu and as a blue belt I am trying to learn to give up the aspect of "winning or losing" in sparring sessions which are for training.  Instead to embrace training for the sole purpose of learning which easily becomes clouded if you are just focused on winning.  My teacher, Master Leo Dalla, tells me to relax and have fun.  He recently said, "If you win every match with the same three moves, you are not learning anything."  It is difficult for me to let go of the winning and focus on the Jiu Jitsu (as I am naturally competitive) but I will do it.

The lines that start, "Things arise and she ..." and "things disappear" makes me thing about the natural flows of the universe.  The Master wishes to be in harmony with the natural order of things, trusts in that natural order and trusts that the Tao, or universe, can act through him/her.  Thus she does not act.  She does not force actions... instead she finds, and knows, the right actions to do at the right time.  Thus, she acts without doing anything because her actions are not forced, she just "does the right thing."

Think about that - wouldn't it be cool to always just do the right thing.  To just do what you should be doing and to let the universe tell you what that should be.  That is being in harmony with the universe.  Think about this in the case of making decisions - what if instead of making decisions, the right decisions would "arise by themselves".  I have seen this in action where a group is desperate to get to a solution so they "force a solution" instead of "finding the right solution."  The best decisions are discovered, are found, and not forced. I think a great example of just knowing what to do is the story of Jesus healing the blind man on the Sabbath.  I don't believe Jesus made a conscious decision; instead, he just did what was right, what came naturally from the Tao, what flowed from his Father without effort.  He did not worry about man's conventions ... instead he did what was right.
