The four types of death represent different levels of cleansing.
Stoning – Stones are building blocks. A stone, אבן is another word for ‘a letter’. Letters are the building blocks of existence. People who go against the words of God by practicing different form of idol worshiping are stoned for cleansing.
People, who curse, speak negative words or corrupt their channel of Yessod (negative sexual relations) are also stoned. The words of God are the ‘stones’ that cleanse these kinds of negativity.
Burning – This cleansing process reserved for those who corrupt their connection to Binah. A daughter of a Kohen that had sex with another man when she was married was burned for cleansing. A man that had sex with two women of the same spiritual line (like mother and daughter, daughter and granddaughter) when he was married to one of them got burned for cleansing.
Those who practice witchcraft are also cleansed by burning because they connect to Binah of the negative side.
Other than death by direct fire, illnesses that generate high body heat are also considered death by fire.
Death by Sword – Killers and those who conspire to kill another are cleansed by the same method they had planned to kill the other person.
Most illnesses that end with death are related to choking, or burning. Car crashes can be the aspect of stoning. If any object pierces the body and causes immediate death or bleeding to death it is considered as death by the sword.
Choking – Cleanses false prophets and those who disrespect their parents.
All impurities of the soul must be cleansed by any or all the types of death. That is why some infants or young people die. They come for a short correction to cleanse ‘left over’ Tikkun from previous lives.
Death by a ‘kiss’ is when the soul leaves the body without any trauma or pain. It comes to righteous people or those who completed their Tikkun. Some righteous people accept traumatic death to support the cleansing process of the generation.
To avoid these types of death one should be careful about his words, make spiritual connections, study, and read sacred texts.
Before we go to sleep and while we are lying in bed we should meditate and accept on ourselves all four types of death. It helps our soul to get cleansed before ascending for a spiritual rest of the night. The other reason is that if that night we die in bed then we are better prepared for the next phase of life.
