法華玄義釋籤 1.56

1.56

「迷涅槃道」去明流轉後忻樂小乘，如人迷故謂東為西，則東西俱失。三德涅槃即理而具，謂理為遠、背大取小則大小俱迷，謂大為遠為迷大，謂小為極為迷小。

From "deluded about the path of nirvāṇa" onward, it clarifies that after transmigrating, they took pleasure in the Small Vehicle. Just as when a person is lost and takes east for west, both east and west are lost. The three virtues and nirvāṇa are inherent right in the principle; thinking that the principle is distant, they turned their backs on the Great and grasped the Small, so that they were deluded about both Great and Small. Thinking the Great to be distant is being deluded about the Great; thinking the Small to be the ultimate is being deluded about the Small.
