When you are present, you can allow the mind to be as it is without getting entangled in it. The mind in itself is a wonderful tool. Dysfunction sets in when you seek your self in it and mistake it for who you are.
As far as inner transformation is concerned, there is nothing you can do about it. You cannot transform yourself, and you certainly cannot transform your partner or anybody else. All you can do is create a space for transformation to happen, for grace and love to enter.
The reason why the romantic love relationship is such an intense and universally sought-after experience is that it seems to offer liberation from a deep-seated state of fear, need, lack, and incompleteness that is part of the human condition in its unredeemed and unenlightened state.
So the single most vital step on your journey toward enlightenment is this: learn to disidentify from your mind. Every time you create a gap in the stream of mind, the light of your consciousness grows stronger. One day you may catch yourself smiling at the voice in your head, as you would smile at the antics of a child. This means that you no longer take the content of your mind all that seriously, as your sense of self does not depend on it.
Enlightenment means rising above thought, not falling back to a level below thought, the level of an animal or a plant. In the enlightened state, you still use your thinking mind when needed, but in a much more focused and effective way than before.
See if you can catch yourself complaining in either speech or thought, about a situation you find yourself in, what other people do or say, your surroundings, your life situation, even the weather. To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself a victim. Leave the situation or accept it. All else is madness.
