From The Letters of Rennyo Shonin (Gobunsho) Fascicle 5, Letter 3
Women who remain in lay life should realize and never entertain the slightest doubt that those who, without any calculation, deeply rely on Amida Buddha single-mindedly and unwaveringly, entrusting themselves to the Buddha for their emancipation in the afterlife, will all be saved.
This is the intent of the Primal Vow of Other Power, the vow of Amida Tathagata.
Beyond this, whenever they feel joy and gratitude for their emancipation in the afterlife, they should simply say “Namo Amida Butsu, …”
Humbly and respectfully.
