This theory makes sense to me in my mind, but when explaining to people its quite hard to do, I've attempted a diagram but it isn't very clear.
LoA is Line of Attraction, this is formed the moment two people make a connection with each other which has the potential of becoming a relationship of some kind. This is not limited to guys and girls but for the purpose of removing confusion I have used male and female as an example. Each party's power is represented by the cone on it's side so they overlap.
Both parties believe they have the power in the potential relationship. Neither realises that their power lies more prodominantly in their own understanding of reality, which is represented be being more on their side of the LoA. The circles around them represent their power, and the the power extends towards the other person and more into the other person's plane of understanding gradually is weakened.
If A and B form an attraction, at the furthest away from B, A has a power level of 10, for example. With every increasement towards the B the power is reduced. B also has a power level of 10 on their side of the LoA. If 5 for both parties is the LoA then at A's 6 it will be B's 4 and visa versa. At A's 9 (it's second most strongest power level), B's will be only 1.
The reason for these power levels is quite simply because no one can understand another person's perspective of understanding, as we have only experienced our own lives and no matter how much another's life can be explained we will never know anything other than what we can compare to ours.
Since in their own understanding their power and influence is constant, we don't feel like either one of us is being manipulated at this early stage in attraction. Since both feel that they have power of equal or greater strength they allow them to grow closer to the other as they feel like it is a concious decision that they allowed it to happen and that they are in control, when infact neither are.
As long as an equilibrium of power is maintained then it is likely that the gravity of the LoA with encourage both to grow together and a relationship to form.
Edit: I hope it makes sense, it is 4am afterall.
