When the soul is finished with this lifeline, it reviews all that it has done and accomplishes, including all that it has done to others, both positive and negative experiences. The soul-personality, along with its Oversoul make the decision about where, how, and if the soul will progress. The soul-personality may get "stuck" in this review, especially if the lifeline was extremely negative, continually reliving its life until it can progress. Sometimes, when there is unfinished business, the soul-personality may become "Earthbound" until it feels it has completed what it needs to complete. Eventually the soul goes where the mind-pattern pulls it. For example, if the person believes in heaven and hell, the mind-pattern will create that for the person until they can accept something else.
Committing suicide is against Universal Law, and when this happens the the soul-personality, in conjunction with its own Oversoul, sets up a situation even more severe than the one the soul-personality left behind. The idea of physical reality is to overcome specific mind-patterns. The lessons, even here, become increasingly harsh, until the soul-personality "gets it" so they can release it and move onto something else. If someone thinks that life is tough now, it gets even tougher under these circumstances.
Anyone contemplating suicide should seek immediate help, because when a person thinks that he/she is at the bottom, he/she should always remember that it can always get worse, whether in this reality or another.
Every soul-personalty sets up his/her lessons for a reason. Find the reason, work through it, and move on. Do it now, before it becomes more complicated and you find yourself in a worse situation.
