From The Letters of Rennyo Shonin (Gobunsho) Fascicle 1, Letter 6
I don’t know why, but recently (this summer), I have been particularly subject to drowsiness, and when I consider why I should be [so] lethargic, I feel without a doubt that the moment of death leading to birth [in the Pure Land] may be close at hand. This thought makes me sad, and I feel in particular the sorrow of parting. And yet, to this very day I have prepared myself with no lack of care, thinking that the time of birth might be imminent. All I continually long for in regard to this, day and night, is that, after [my death], there will be no regression in those among the visitors to this temple whose faith is decisively settled. As things now stand, there should be no difficulties if I die, but each of you is particularly lax in your thinking in regard to birth. As long as you live, you should be as I have described. I am altogether dissatisfied with what each of you has understood. In this life, even tomorrow is uncertain, and no matter what we say, nothing is to any avail when life ends. If our doubts are not clearly dispelled during this life, we will surely [be filled with] regret. I hope that you will bear this in mind.
This is entrusted to those [assembled] on the other side of the sliding doors. In the years to come, please take it out and read it.
Written on the twenty-fifth day of the fourth month, Bunmei 5 (1473).
