Sir Lal, are the people who say that suicide is bad and leads to apayas telling the truth? A person may commit suicide because of a strong emotion such as anger and grief.
However, puthujunas who lay down their lives for the sake of others do punna kamma.
Ariyas can do this without consequence. Anathapindaka’s daughter was a sakadāgāmi. She committed suicide by starving herself to death. She had not found a husband. After her death, she took birth again, in the Tusita paradise.
