In believing in complementary duality in all things, I believe we are constructed of two extremes: the fear self and the warrior self. These two give birth to the instance of yourself right now, just as the Everything and the Nothing conspired to create this world of Something.
The key of all yanantin is balance, and in this case it is the balance between fearsome and fearless states. It is not that the fearless warrior is who you should strive to be! It is not that we need to remove and deny all fear. The dichotomy is not good vs. bad here. Everything has its place: fear can keep you alive, or at least keep you from doing senseless things. Complete fearlessness on the other hand can lead to a lack of real love, for what is love without a fear of losing it? (What is having anything without a fear of loss?) That is yanantin, the acceptances of opposites as necessary points on a spectrum between which we seek the wisdom of balance.
