Time is never running out of due to re-birth.
Time is always running out due to re-death.
From your letter, I see that you are diligently ﬁghting bad habits but have not yet obtained results. This is because you are not truly concerned about the issue of Birth and Death [being trapped in rebirth], nor have you internalized the method that helps people to “transcend the human realm for that of the saints [Buddha and Bodhisattvas],” sever delusive karma and achieve pure thoughts. That is why you have failed to achieve true results.
You should always ponder this truth: “It is diffcult to be reborn as a human being, it is diﬃcult to learn of the Buddha Dharma, it is difficult to encounter the Pure Land method. I am fortunate today to have been reborn as a human being and am in the favorable position of having learned about the Pure Land method. How dare I waste this limited lifespan on evanescent form, fragrance, fame and fortune? How can I resign myself to an empty life and useless death, wallowing along the Six Paths [of rebirth] – with no end in sight?”
You should paste the word “death” on your forehead, so that when you meet with various circumstances unworthy of attachment, you will immediately recognize them as boiling cauldrons and ﬁrepits that can only harm you. In this way, you will not be like a moth, freely choosing to ﬂy into the ﬂame and burning to death.
