The Essence Principle of Life Force, called God by most people, is One. This is realized by a rare few; though science is pointing, more or less, to this fact - that All is indeed One.
Even if it is not individually attained - not 'witnessed' as if - once it is realized in theory that "All is One", we should function from "this": All Pervading Principle of Oneness.
This "Kingdom of Heaven" - of Oneness - is "Within" our quintessence, and being. Attuning to 'IT' therein, in time, all that happens to us or around us, shall start appearing like a dream - a play 'within' One Self.
In One, there is no "other". All is a Single, Whole. "I and my Father are One", as if.
Remembering the Unity Principle, whatsoever happens, shall be 'witnessed' as a Cosmic Principle of Oneness. Waves are a natural phenomenon 'within' the ocean - there is no 'good' or 'evil' in this process. Similarly, is the case of human life, and destiny.
There is no 'good' or 'bad'. Only that happens which is meant to happen, as is the Law of Nature. Of destiny.
Accepting that whatsoever happens, does so by the dictum of Oneness, we shall be able to let go of both 'good' and 'bad' - accepting it as a natural 'happening' as per one's destiny.
In acceptance lies the Key to Knowledge of That Which Is.
One it is accepted, that Essence of Nature is One, all 'happening' and 'non-happening' ceases to bother an Enlightened One.
An 'Attained' One takes destiny in his or her stride, becoming stronger by the day. And firmer, in Unity Consciousness - that forms the Basis of What Is.
