Shinjin [arises] through the Buddha's power, thus, is difficult, difficult! "
"Truly we know that the supreme, perfect fruit of enlightenment is not difficult to attain;
it is pure shinjin, true and real, that is indeed difficult to realize."
Passages on the Pure Land Way
"Great shinjin is rare, most excellent, true and wondrous, and pure. Why? Because the ocean of great shinjin is extremely difficult to enter, for it arises through the power of the Buddha; because the true land of bliss is extremely easy to go to, for one is born there immediately through the power of the Vow."
KGSS, page 227.
"To go is easy and yet no one is born there. To go is easy: When persons allow themselves to be carried by the power of the Primal Vow, they are certain to be born in the land that has been fulfilled through it; hence, it is easy going there. No one is born there: Because people of true and real shinjin are extremely rare, those born in the true fulfilled land are few. Hence, Master Genshin states that those born in the fulfilled Pure Land are extremely few; those born in the transformed Pure Land are many."
