Kisa Gotami was blinded by grief at the loss of her son. She wanted medicines to revive her child. Someone directed her to Buddha. Buddha could help her only if she could procure mustard seeds from a house that has never experienced death. Unfortunately, Kisa Gotami failed to find such a house inspite of a long struggle. Kisa realised that she had become selfish in her grief and death is common to all. Buddha explained to her that humans are mortal beings. Sorrow or lamentation cannot bring the dead back. The wise understands this fact and draws out the arrow of lamentation and becomes composed.
