SUICIDE or any death is ONLY the death of an earth container for the soul. Loss of the biology changes nothing for the infinite soul aspect. Any spiritual or emotional or dark thought patterns or contracts the soul had when the biology died the soul still has. When they reincarnate into another biology or form — the same issues remain. The moral dilemmas the soul essence had before it left a body will be the same afterwards and always, until its thinking changes.
There is no spiritual value in suffering in a body or form in spite of what a religion or society may say. There are NO “Brownie points” — a hypothetical social or spiritual currency, which can be acquired by doing good deeds or suffering in the quantum field. Suffering and sacrifice are only “a thing” in the quarantined third and fourth dimension or dark bandwidth.
Spiritual reasons for leaving one’s biology may be that your soul has completed the mission it entered a body to accomplish. Sometimes infants die in an effort to create compassion in those around them. Some children and adult bodies are soulless, leaving the biology vulnerable to disease or accidents or mental illness and hopelessness. The soul makes agreements with other souls before incarnating into a form. When one or both side of the contract do not honor the contract they may choose to kill their body. Some souls commit suicide to honor their truths.
The human(s) left behind, after a death or suicide frequently wallows in guilt shame or abandonment. They are making the death all about THEM what they needed or wanted, instead of honoring the law of allowing. Honoring the choice of the one committing suicide. The “loss” is mostly an illusion. If you want to commune with the soul that left its biology, COMPASSIONATELY go within you and call their name, when you feel their presence ask questions and or explain things and your feelings to them.
