Contemplating the power of Tathagata's Primal Vow, One sees that no foolish being who encounters it passes by in vain. When a person single-heartedly practices the saying of the Name alone, It brings quickly to fullness and perfection [in that person] the great treasure ocean of true and real virtues. - Shinran Shonin

"To know by thinking falls into the secondary. To know without thinking falls into the tertiary." (Yangshan Huiji, X1405p58b18-19; tr. JC Cleary: A Tune Beyond the Clouds, p 43)
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind." (Gampopa to Düsum Khyenpa, in "The First Karmapa", KTD Pub, p 254)
