Right and left, heads and tails. Freedom and responsibility, capitalism and socialism.
Life isn’t one-dimensional. We need to maintain a broad perspective, juggling often competing values, the complexities of human relationships and our internal gravitational pulls.
In Judaism, we see this reflected in the fact that Mitzvahs come in two general flavors: Dos and Don'ts. Behave this way, and not that way.
We can find these two elements in any strong relationship. The foundation of a meaningful bond is basic respect. We restrain ourselves from doing anything that might intrude on this meaningful connection. First, do no harm. But that's not enough. We need to also pro-actively build the relationship, creating avenues for further depth and beauty.
This also frames our relationship with G-d: By respecting the Don'ts, I declare that my momentary impulses aren't as important as my connectedness to the Divine; it's like controlling your temper at home, because the family cohesiveness is so much more important.
In performing the Dos, I’m finding opportunities to fulfill the desire of a Loved One. It's like bringing home flowers to show how much you care.
