As Jodo Shinshu Sect denies the notion of boso (the properties of a grave, such as its style and shape, which may affect one's fortune) as a groundless superstition, it prohibits the building of Kissobaka (a grave with properties which may lead to good fortune).
墓の形によって人生の幸不幸が決まるという墓相などは根拠のない迷信として否定するので吉相墓の建立を禁止している。
