How long does it take for a person to cycle from birth to death?

Samsara, which is not specific, depends on the chance. It is a particle reincarnation with little memory. It is usually put down during the journey, just like a person had a dream. After several years, will you remember that dream clearly one day? Even if something touches you one day, you are in a trance. A soul without a body is weak. Most of the time you are in a tired sleep, and occasionally your consciousness only flashes for a few seconds. Only when you meet a new body will you have some consciousness and perception based on the body. It may be a plant or an animal. After such a long time, the memory of the past will disappear, so it is difficult to reincarnate into an adult, so cherish everything now, because you have to ask how long it will take, maybe more than a year after death, maybe thousands of years to reincarnate into an adult, or even disappear!
