佛說盂蘭盆經疏 2.66

2.66

"If anyone makes offerings to these monks of pravāraṇā, their current parents, six relatives, and family members will escape the suffering of the three wretched realms, attain liberation immediately, and have clothing and food naturally. If their parents are currently living, they will enjoy blessings and joy for a hundred years. If the parents of seven lifetimes have been born in heaven, they will undergo spontaneous transformation birth at will and enter the heavenly radiance of flowers."
