Choose a quiet environment, hold up the index finger of your right hand and press the belly of your finger lightly against your eyebrow.
Close your eyes, relax your whole body, don't have any distractions and concentrate.
Mindfully look at the darkness on the brow where your finger is pressed, and slowly you will see it.
The process goes like this: first there is a darkness, then you see a bright spot.
It gets bigger and bigger. Finally it becomes a piece like a TV screen.
What you see there is what you have experienced in your past lives, it is as simple as that.
As long as you have the memory of your past lives, you should be able to see.
Although you may live many lifetimes, you can see as long as you have memories, especially the one that is deepest in your memory.
The first time is the most real, and if you try again, it may be because what you saw the first time was too shocking to really concentrate on.
If you can't see, it could be that the memory is too small, or not strong enough, or it could be that the previous life wasn't in the human world!
