When you want to pray and meditate for someone else’s well being, you need to assess your own attitude to the situation. As a former yoga teacher of mine was fond of saying: you have the right to the action, but not to the results of the action.
Once you pray and meditate very soulfully for someone else’s well-being, once you invoke the assistance of the spiritual figure or energy you are requesting the assistance from, once you identify soulfully with the person you are seeking to help, then you need to do two more things:
First, you need to pray that all action is done for the highest good of all involved. Then you need to detach yourself from the results. This is because it may well be that the person being prayed for desperately needed the situation in order to learn lessons they could not learn anyway else, or that they willingly took on the situation to help someone else in some way. You yourself cannot know the full ramifications of the issue.
