siblings in another life?

How do you know if you were siblings in a past life with some one?
My gay co-worker says i was his sibling in another life, is there a way to see
if we might be comected?

Well, if you are aware of past lives, or think you can remember some details, remember as much as you can and write it all down or record it on your computer, whatever floats your boat. Make sure you make it as detailed and descriptive as possible.

Then, sit them down and have them do the same, but don't help them or show them what you've written already. Have them describe in particular the past life they think you are a part of in as much detail as possible.

Then, once both of you have done this little exercise, you can 'compare notes' and see if what they wrote and you wrote match up.

If you don't remember any past lives or don't believe, whatever, then I guess you're kind of stuck as far as I know.

I'm basically providing this advice based on the assumption that you remember some past life activity as well. Hope this helps.
