The Fourth of Ten Wrong Paths – Four Fallacies on Finiteness and Infinity
“Further, when the good practitioner’s mind is firm, clear, and proper in the cultivation of Samadhi, no demon can disturb him. He may then thoroughly investigate the origin of all categories of living beings, and he may contemplate the source of its subtle, clear, and constant movement. But if he begins to speculate about the existence of distinctions, he could fall into one of the four wrong views about finiteness and infinity:
“First, as he sees that the origin of life continues to flow and function without ceasing, he may come to the conclusion that the past and the future are finite, while the continuity of the mind is infinite.
“Second, as in his Samadhi he is able to see living beings up to eighty thousand eons back into the past, and cannot see or hear anything earlier than that, so he regards the expanse of time where nothing is heard or seen as infinite, while the expanse of time where he can see beings as finite.
“Third, he regards his own pervasive awareness as infinite and the awarenesses of all other people, who appear within his awareness, as finite, since he cannot perceive the nature of their awarenesses.
“Fourth, as he tries his best to put an end to the mental formation skandha, based on what he has figured along the mental pathways, he speculates that in each and every individual being, half of their being is living, while the other half is dead. Therefore, he comes to the conclusion that everything in the world is half finite and half infinite.
“With such speculations about the finite and the infinite, he takes a wrong path and becomes confused about the nature of Bodhi. This is the fourth wrong path, constituted by four fallacies on finiteness and infinity.”
又三摩中诸善男子，坚凝正心，魔不得便。穷生类本，观彼幽清常扰动元，于分位中生计度者，是人坠入四有边论。一者、是人心计生元，流用不息 。计过未者，名为有边；计相续心，名为无边。二者、是人观八万劫，则见众生，八万劫前，寂无闻见。无闻见处 ，名为无边；有众生处，名为有边。三者、是人计我遍知，得无边性。彼一切人，现我知中，我曾不知彼之知性 ，名彼不得无边之心，但有边性。四者、是人穷行阴空，以其所见，心路筹度，一切众生一身之中，计其咸皆半生半灭 ；明其世界一切所有，一半有边，一半无边。由此计度，有边无边，堕落外道，惑菩提性，是则名为第四外道 ，立有边论。
