Before a person dies, almost exactly near about nine months before, something happens. Ordinarily we are not aware, because we are not aware at all, and the phenomenon is very subtle. I say almost nine months because it differs. It depends: the time between the conception and the birth will be the time. If you were born after nine months being in the womb, then nine months. If you were born after being ten months in the womb, then ten months. If you were born after seven months in the womb, then seven months. It depends on the amount of time between the time of conception and birth. Exactly the same time before death, something clicks in the hara, in the navel center. It has to click because between the conception and birth there was a gap of nine months: nine months you took for birth; exactly the same time will be taken for death. As you prepared nine months in the mother’s womb for birth, you will have to prepare nine months to die. Then the circle will be complete. Something in the navel center happens. Those who are aware, they will immediately know that something has broken in the navel center; now death is coming closer. Approximately nine months.
