This is a miss-understood quote from Rumi , a 13th Century poet and mystic of his time.  

The quote was pared down by a magazine writer and has somehow taken on a new meaning, other than the intended from Rumi.   She has done some research, as she does, so as not to assume to much.

She learned it really is more about the man and his faith and differences between Islam and other religions of the day. It is more about the coming together outside of each individual one, and it is believed that "the field" represents death and the place outside of normal lives where the 2 will meet and effectively not be at odds with each other, as many religions are. 

She has read several other possible meanings, which she finds, in the 21st century, to more ring true.

as stated in one bit of information:

most other mortals live in a world wherein the concepts of “right” and “wrong” control the paths we take. Each of us - through accident of birth - are placed where we are and in those places “right” and “wrong” have their own unique meanings, but the meanings are not universal and will have different meanings or understandings. Somewhere or some when (time), there is a place where the concepts of right and wrong are not controlling, they are moot points no longer of concern.

As a child she, she was raised in the baptist church. She grasped the understandings, the teachings and the rights and wrongs as laid down by the bible.

As she grew older, while she still believes in many of these teachings, she was put off by much of the "must do's" and hard and harsh ways that some people in the church tried to make it the Be All/End all of every day living.
This turned her off.  (as well as the hell fire and damnation yelling at her from the pulpit)  

She admits she has returned, somewhat, but. there are thoughts that she has gathered in her storied life that override what the bible teaches and some of the preaching holds no meaning.. other parts.. maybe..  in many instances, she has "forgiven" herself her wrong doings and actually feels that God has controlled that part as well and has moved forward in learning and growing. 

She discovers that she has lived a life more freely (depending on how you look at it)  than others she has known, this might be her downfall eventually, but she likes the ability to be able to come to her own decisions about directions and what she can and cannot do with her life.

She must also explain that she hasn't gone "to the dark side" and grabbed hold of the parts of the world that are far outside of her upbringing and nature. She doesn't mind listening to what some might think but in others she finds the whole concept of some teachings a bit.. well.. ridiculous.

She does, however, feel that Karma, Fate and the Universe, Serendipity, time and place, do, in many cases, play very important roles in much of her life. she hasn't been lead to this feeling by anyone, but has been able to see it work in her own life on occasion. In the right place at the right time and the like. she also feels that sometimes her life is guided by other forces (think The Adjustment Bureau film, as if someone has laid it out and there is no turning right or left.. only straight forward) and she manages, in her way, to deal with it..

When as a young adult, the fact that she had craved the water and sea, and carried a strong feeling that she always wanted to live on an island, now isn't lost on her, considering her current circumstances.. (at the time, it may have just been a thought.. but that's all it really had to be) 

Her take on this saying goes like this.

There are definitions of wrongs and rights in this world. Many of those are here and now because of people in the past  making those decisions for us. ( and remember these are from the bible.. but it's also mans definition of what is written there)

Her feeling is that we have the brains that "god" or whatever force you believe in, gave us and it is our decision to understand and acknowledge, or not, those rights and wrongs. Each person is different in their interpretation, which is basically why these decisions are still with us (ancient in some cases) and it's also why some done't ever venture far from the intended meanings.

Life.. happens.  How we choose to live with it, or resist it, is entirely up to us..

For reasons unknown to the author or the reader, Fate has brought them back together from a much different place, to the here and now. she feels there is no cut and dry answer as to how this will be dealt with or if it will or should be.. 

She is aware that there are feelings that transcend this time and this place and they have been held in a state, not to be lost, and that, in and off itself is significant. 

she feels....

There is a place , a field,  if you will, out beyond each of their own definition of rights and wrongs.. (whether biblical in nature or not)

 She chooses to meet him there. when the time is right and the universe is OK with it.

(she hopes that there is an understanding to what she has written and if not, a discussion can happen)
