I want to know is there a way out to talk to someone spiritually even after losing all contacts due to some misunderstandings?
Is there a way out with any spiritual means to mend up a broken relationship?
Yes, there is a way to begin to reconnect. It is a special prayer by Paramhansa Yogananda, called the Peace and Harmony Prayer. Simple though it is, we have seen it work near-miracles in personal relationships. Here is an article about it.
Although its original use was for personal relationships, in 2016, all of us at Ananda Village (and many other Ananda centers as well) are expanding its application to focus on world peace.
So I suggest that you let the prayer be your first step, and see what kind of opening develops.
