Past lives exist. You can bring memories of them into your present consciousness. It is even possible that you made decisions about your current life incarnation based on what your soul experienced in past ones.
But, for the purposes of having a clear, allowing vibration right now, past lives are, um, irrelevant. Just like a conversation you had yesterday, unless you think about it and call it back into your present moment, it does not affect you.
Your vibrational climate – which is your point of attraction – which is everything – is current. It’s current.
That being said, sometimes you do remember a past life. Or you feel like you've gone through something before. Or you know you have met that person before, darn-it! Should you look into it? Should you try to heal it? Should you get hypnosis and record the story for your own curiosity?
Over the years I have found this to be a delicate balance...
...but only because I spent years, before I learned about Law of Attraction, chasing healing and digging into painful past life experiences only to dredge up more reasons to need healing and help working through past-life experiences that were making me feel horrible in the moment.
My current stance is this: If I am called to look into a past life of mine from a place of inspiration or solution, I go for it. If I am worried about a past life or I think my issues are based on some terrible past life experience I had, I look to the present instead and manage myself here and now.
This keeps my power with me, right now, and not in some other time.
P.S. We sometimes do have an idea for what we want to accomplish or experience in a lifetime before we are born. But the moment we land here on Earth we are free, encouraged, and completely will-powered to do whatever the heck we want. Like going to the park with a jump rope only to realize you want to play on the swings. Like that. And just as fun, soul-wise.
P.P.S. Let yourself play on the swings.
P.P.P.S. If you want to.
Wake up your intuition and make friends with your mind. You're in for the time of your life.
