There are innumerable modes of entry into the Buddha’s teaching. Just as there are in the world difficult and easy paths —travelling on foot by land is full of hardship, and traveling in a boat by sea is pleasant—so it is among the paths of the Bodhisattvas. Some exert themselves diligently, while others quickly enter Non-Retrogression by the easy practice based on serene trust. […]
All who are mindful of that Buddha’s infinite power and merit will instantly enter the stage of Non-Retrogression. So I am always mindful of the Buddha Amideva. […]
With whatever merit I have acquired in this and previous lives, I wish to be in the presence of the Buddha Amideva and attain eternal purity of heart.
—Arya Nagarjuna, Dashabhumika-vibhasa
