If people had more knowledge of walk-in/soul exchange phenomenon, wouldn't it decrease the suicide rates?
Instead of the person taking away their own life and creating karmic debt due to a violation of their life contract, they should ask in prayer or meditation for an advanced spirit from the spiritual plane who is willing to resume this person's responsibilities, so the original soul (the one who is depressed/suicidal) can go "Home" without any repercussions.

I saw a video on youtube of someone who knew someone who begged "God" for over a year to let her "leave" before the transition took place. And others have been begging "God" for years and nothing has happened yet but still determined to leave.
