Mathematics; Dasoham - Soham - Ham

In the chapter of the Bhagavad Gita part 1 Dashoham - Soham, Baba explains the three steps to peace.

Dasoham is first step, that is Duality (Dwaitha, I am the servant of God.) There are two 'I' and 'God', that is not oneness, that is 1 + 1 = 2.
The Da has to be given up. Then it is Soham state (Visishtadwaitha, qualified-non dualism) that is not oneness, it means 'I am Brahman' there are qualified non-two - I and Brahman. 1 and reflection of the self is qualifed non-two. (Brahman and Atman are same, reflection of the eternal, the inner light and self.)
So has to be given up, what is left is Ham.
Ham is Adwaitha state - oneness only One, I am I. 1 and 0 is 1 or total non-two. (Duality, qualified non-duality and total non-duality, oneness or unity)
He tells that 'I am Brahman' becomes a reflection of the inner being - the parathibima...like that word - parathibimba (image of the reflection of the inner being) I would call it - self, light of self, reflection of the light..., I and the self is quailifed non-dualism.
We are individuals and we are different, so the images are also different. Baba explains, when the individual is one, eventhough the object and image is different, there is a link between the two.
That was my question. How is it possible that between two different individuals, who live miles away, different images, different objects, can be a realization of oneness, unity?
That seems practically impossible, because everythings seems different. But he tells there is a link. But that is Visishtadwaitha, qualified non-dualism.
And now he goes on:
Only when the object is omnipresent, there is no place for the image or reflection. There is no room for a separate location. That is why it is Adwaitha or total non-dualism. That means if we know we are only observer, we both are only 'I am I' that is the same - and the object is Baba, and he is omnipresent, so 0, that means it can be One only, because there is no place to go.
That is mathematics! 
One and one is two. One and one only as reflection is qualified non two... and One and the infinite eternal principle - is One. 1 and 0 is 1.
The omnipresent is 0. If we project Baba in the body, then it is 1 + 1 = 2
If we see in him the self, the light, but as reflection of the eternal being, then it is 1 + reflection of 0 = qualified non 2. If we see in Baba God, omnipresence, then it is 1 + 0 = 1, total non-dualism, unity only, oneness, that is the highest state of consciouness and therefore, we can be on the other side of the world and be the same...
