“Seek refuge in the Almighty Spirit. By the divine might of His promise, by the Infinite One was Paradise created; yea, and the Souls of men that dwell therein. And there is nought that may compare with them.” (Buddhist Psalms 1:25)
There is none other in which our refuge should be taken except Amitabha.
It was by His power that the Kingdom of Light and the paradise worlds were created, as well as the souls of humans. In the same manner, it is only by the same power that we can be saved from this world and brought to the Other Shore, and not by that of our own.
