reason for everything but fate

"I don't believe because at school I learn there is a reason for everything" (13).
I feel Omishto puts too much faith in the laws of science and reason. From personal experience I know that science can explain the logic behind certain events but not necessarily the reasoning. I suppose science can give a logical reason for Omishto not realizing that her dress had blown away. Logically she could have been in shock from all the dramatic events occurring in her environment. But her dress must have been torn off her body by the wind. And yet, she is consumed with the image of the horse. Personally, I think the horse instills a lasting emotion in Omishto. The horse is a part of the natural world which she cares so much about. On the other hand is only a dress and has little meaning to nature. She must have felt the dress being removed by the wind. But the horse creates a lasting emotion. Death in itself lasts in your memory longer then minor pains in you endure, science can explain this fact. But why in the middle of the storm does she happen to run into the horse? At the instant she finds the horse she could have been inside or anywhere else. If the wind were to force the dress off an instant sooner, I wonder if she would have noticed the horse that suffered as a result of nature.
