People often whine about "their bad karma"; usually those things they're faced with in life that they perceive as challenges or obstacles. I'm not altogether sure how to make sense of reincarnation or how choices made in the past could end up impacting the future. And it gets pretty dicey when we try to discern the reasons why some people are suffering while others appear to have an easy life. The chain of events that form our lives as they are today are very complex and mysterious so it’s best not to get too caught up in the prequel and instead simply deal with this movie we find ourselves in.
We all have to cope with circumstances that are less than ideal—that just comes with being alive. It doesn’t matter how we got to where we are today because all we have is right now. What matters most is what we do with our present situation.
To borrow the often used analogy, don't stand around questioning where the arrow in your chest came from, just pull it out.
Paying someone to tell you who or what you were in a past life is ludicrous and a waste of time. If you believed you've lived before and want some insight into your past incarnation, then simply look at your life as it is right now. That will tip you off to all of the decisions you made before. Everything comes from something. If you plant an orange seed, you get an orange tree. Just figure it out without attaching to the endless list of possible reasons and stories and explanations.
What we don't realize is that what might look and feel and smell like bad karma could really be our saving grace. The things that suck about our lives are the things that leave us the most room for growth. They can be our tool for awakening so we can better help ourselves and other people.
When we see our karma as nothing but punishment for past deeds, we're more likely to be complacent and fall into self-pity mode. Using use our life situation as an excuse rather than as an impetus to give to the world in some way means that our karma is using us.
So instead of getting wrapped up in how you may have arrived at your own particular version of misery, and why things seem to suck as much as they do, you can take what you have in this life, both the good and the bad, and make use of it.
Use your present situation in life to help other people no matter what it is. At the very least you can pray on your pain in the hopes that no one else has to feel it as you do. Or at the most you can find some way to help alleviate it in someone else.
So instead of letting your karma get the best of you, use it to full advantage and transform it into your own unique means of saving all beings everywhere.
Or for starters, help just one person.
