Let's understand these terms and how they all tie up in understanding Awareness, Consciousness, Beingness, or God. By those names I mean the same Infinite One Being. Some might find any or all of those names difficult. So let's clarify that first.
There are many names that are used for God or That Which Is. It is not here considered that God is a bearded man in the sky, watching over humanity. The God discussed here is much more personal than that, yet impersonal. That sounds confusing maybe, but what I mean is that the Impersonal is at the heart of all persons. The core of our being is That Which Is. God is that essential impersonal nature that gives life to the world and allows the appearance of personal beings, such as humans and animals.
This is the Immanence of God, being within all beings. Immanence means that God is within. Many of us seek that inner peace and stillness that is God's nature. Some people seek the Infinite Stillness within. Some people feel a personal relationship with God, which is a path to God. It is the path of worship and devotion, where the personal relationship draws the apparently separate beings towards the Infinite Being of God.
God can also be considered as Omnipresent, being everywhere present. The reason for this is that although God may seem to be at the heart of all beings, the heart is infinite. Nothing is outside of God. Limits are illusory. There really is only God.
Yet we can also consider God as Transcendent. That means that God is beyond the world. So how can that be? God does not appear in the world. God is beyond the appearance of the world, yet the world appears within God.
So firstly I said that God is within (Immanent), then I said that God is everywhere (Omnipresent), and then I said that God is beyond the world (Transcendent). You may think, "C'mon, Dave, make your mind up." But really all three are acceptable references to the nature of God. The three are one, you could say.
The world appears as if God is the heart of our being, and in seeking God within we find the Peace of God (some may also call it the Kingdom of God). However, God's Peace is without end. God is timeless and formless. So we find that God only seems to be at the heart of our being, and in fact God encompasses the whole. God's infinite nature cannot be limited by the appearance of form. God is formless, without end, so God is beyond the appearance of things.
That should neatly sum up God's Immanent Omnipresent Transcendent nature. Seemingly contradictory but beyond contradiction. This is the nature of being.
