May all practicers – persons of deeply entrusting mind – single-heartedly entrust themselves to the Buddha's words alone and, thinking not of their lives but relying utterly on the practice [of the nembutsu], abandon what the Buddha brings them to abandon, practice what the Buddha brings them to practice, leave what the Buddha brings them to leave. This is called "being in accord with the Buddha's teaching, being in accord with the Buddha's intent." This is "being in accord with [Amida] Buddha's Vow." This is to be a "true disciple of the Buddha."
—Master Shan-tao, Commentary on the Contemplation Sutra (as quoted by Master Shinran in Kyogyoshinsho, Chapter III: "Chapter on Practice")
The radiant light, unhindered and inconceivable, eradicates suffering and brings realization of joy; the excellent Name, perfectly embodying all practices, eliminates obstacles and dispels doubt. This is the teaching and practice for our latter age; devote yourself solely to it. It is eye and limb in this defiled world; do not fail to endeavor in it. Accepting and living the supreme, universal Vow, then, abandon the defiled and aspire for the pure. Reverently embracing the Tathagata's teaching, respond in gratitude to his benevolence and be thankful for his compassion.
~ Shinran Shonin, Passages on the Pure Land Way
