Life is imperfect!
Yeah! Life is imperfect! And its perfectly okay to accept it this way. In this karmic playground called "Creation", imperfection is vital for its sustenance. If equilibrium reaches every where then what else will follow? So that is why everything "tends" to equilibrium instead of actually attaining it.
World is a temporary and imperfect abode assigned to attain perfection and to merge with the perfect one. Though our actions are imperfect but they are much better than perfect inaction.
