Tariki Hongen:
(The Original Vow of the Pure Land) -
"Hear us, See us. Become us, Eventually."
This is Certainty.

The Difference between Zen and Pure Land is Practice and Faith - Islam is Practice and Iman is Trust. The joining of the two is Perfection.

It is my belief that eventually a Sufi will come to the crossroads of Contemplation (practice) and Faith (trust) and prefer to join them. After all, when all the practices are said and done, eventually there is the Pure Land, or the silence of love in which we dwell.

To stop seeking salvation and become salvation - In the heaven of salvation we have no further need for forgiveness, its work is done. Yet even after we stop seeking salvation and become salvation, which is the work of all true religions, there is still Practice (Zen) and Faith (Pure Land).

Honen and Shinran - Rather than teaching the practice that got you there, he taught getting there by being there. One said that the practice leads to the goal and the other said that the practice is the goal.

Arab arrogance caused people to reject Arabic but the truth had to reach them somehow, for it has never been separate from them.

To quote the book (parentheses mine) -
"Tariki, as we have seen, means Other Power. Hongen, or "original vow" is the very core of the original teaching of Pure Land Buddhism.  (Basically, it's the promise, "if I get it I promise to give it to everyone." - the vow of the bodhisattva.) At the start of his practice to become a Buddha, the bodhisattva Dharmacharya (chariot/shari`at/carrier of Truth) made forty eight vows that he promised to realize when he attained enlightenment. Many of the vows are about the Pure Land - a symbolic description of the state of enlightenment - that he would create when he became a Buddha, Of all those vows, Dharmacharya's "original" or essential vow is his promise, once he has attained enlightenment and become Amida Buddha, that any living being who calls out his name will be born into his Pure Land and attain enlightenment. This is the vow that became the core teaching of Pure Land Buddhism." p88 Reliance upon "Other Power"

Zen and Pure Land - Practice and Faith - Samadhi means Realization (of the Pure Land), it comes after and is the result of Practice/Zen (Dhyana meditative contemplation), if that is the intention. So practice IS Realization (Pure Land), AND the means TO Realization (Pure Land). Realization is not taken away. It is the Salvation of the sinner. It is the soul's primordial knowledge of endless eternity shining through the illusion of temporary life.

5. Detachment from other, 6. Focus, 7. Thought (contemplation), and 8. Realization

Fulfillment is not realization, but a prerequisite. Fulfillment is healing, but saved and saving? That's something way beyond fulfillment.
