The sutta says that one cannot LIVE the householder life as an Arahant.
- A layperson or a householder can attain Arahanthood, but they must become a bhikkhu within seven days, or they will die.
- Santati died the same day he attained Arahanthood. I am not sure whether King Suddhodana died the same day, but he was quite ill and likely to have died within that seven-day limit.
