Hi, Plane-arium!
I know a couple other dualities: positive and negative, attraction and repulsion.
Then there's always:
"To everything there is a season...a time to be born and a time to die, a time to plant and a time to uproot that which was planted, ... a time to weep and a time to laugh, ... a time to keep silent and a time to speak, ...." (Ecclesiates ch. 3)
