They are different ways the same thing is seen from different levels.
At the highest level everything is predetermined, not only marriage but all the experiences of life we must go through in our journey from the darkness to the Light.
At the cosmic level, there is the play of cosmic forces that fulfils the original plan. Here there is a relation between the state and level of our consciousness and the situations and circumstances of our life. Here the play gets distorted due to the action of the cosmic Ignorance.
At the individual level, – and that is the main thing that concerns us from the practical point of view, we have been given a relative sense of freedom of choices. These choices do not necessarily determine the result that we hope or expect, but it does make a difference to the experiences that we draw from it, thereby compressing or prolonging the journey in terms of time.
Trust and surrender to the Grace of course brings in the most powerful element in shortening and fast tracking the journey or even changing the course.
