A Sec 3 student once came to tell me that he had witnessed the aftermath of a suicide at his block. I didn’t ask for details but perhaps he saw the authorities taking care of the deceased’s body.
It was after the lesson and the sharing was rather abrupt. But I randomly suggested, “Maybe you can say a prayer for this person.”
The boy told me that there is no point because in his religion, suicide is a sin for which no forgiveness is possible.
I improvised an answer that did not contradict his faith. I replied that no one except God knows what went though the final moments of a person’s life. Perhaps in the last few seconds, he was repentant. Who knows?
As a Buddhist, I do not believe in a deity who will send a person who has killed himself to hell forever. Suicide is a desperate action from a mind which wants to end suffering. But Buddhism does not recommend this way to end suffering. There is a much better way - the Noble Eightfold Path.
