The feeling was mysterious, somewhat like the Reward Body in Lifetime.
For those who cultivated a Reward Body, whatever they did to the world and whatever impact they made would bring corresponding feedback.
They used that feedback to comprehend the world's true nature, draw ever closer to certain laws, and gradually acquire great divine powers.
The one who had taken the Reward Body furthest, as far as Meng Chuan knew, was Amitabha Buddha—not the Amitabha Great Emperor of Shrouding the Heavens, but Amitabha Buddha, an Other Shore being of Lifetime.
Amitabha Buddha had made forty-eight great vows, received a response from the Great Dao, and attained a perfected Reward Body Pure Land: the Western Pure Land of Ultimate Bliss.
From then on, he was Undying and Immortal.
Creating Other Selves was somewhat similar to cultivating a Reward Body. Heaven and earth gave Meng Chuan feedback, allowing him to discern what traits a Projection of his true self would have in this world. He adjusted it bit by bit, bringing it closer to himself until he obtained a true Projection.
Of course, every world had its own peculiarities. It was like looking in a mirror: the reflection changed depending on which way one faced.
Meng Chuan needed to find the corresponding traits of that Projection. It was a crucial step toward leaving an imprint.
By leaving legends of himself in this world, Meng Chuan had given many people an impression and understanding of the "Great Fiend."
Once Meng Chuan's legends had spread throughout the world, they would form an image of the "Great Fiend" belonging to this heaven and earth. It would resemble a virtual Other Self, and Meng Chuan would need to adjust how people perceived the "Great Fiend."
