My understanding of reincarnation is taken from various sources as they differ culturally . As for suicide one important thing to consider is not the act but the intentions surrounding it. Meaning it's all about head space. In the west suicide is regarded as a negative having to do with various emotions such as depression, sadness, loss etc. However in a country like japan suicide can be a thing of honor and pride so it may be seen as a positive. In the dying process your thoughts are what cary you into the next plane of existence it is important that the individuals projections are clear. What you send out is what comes bak at you. If a person dies in a state of confusion they may not have realized they are dead and may get stuck in that mindset for a very, very long time. This may be what happens to spirits we perceive as ghosts. On the other side a person who dies in a state of peace and awareness can move onto higher realms very quickly. It is well known that when ghandi was shot, he immediately went into a deep state of meditation before he passed and because of this, he is thought to have transcended into nirvana or what evr you may call it. So in a very literal way your mind creates the reality u incarnate into in death.
