大乘起信論廣釋卷第三．四．五 5.124

5.124

論。假使有人至不可喻　釋曰。此思惠益。十善雖多人天漏業。思修雖少佛無漏因。由是過前不可喻。

[Treatise:] If a person [were to teach all sentient beings in a system of three thousand great thousand worlds to practice the ten paths of good action, they would not equal someone who reflects correctly on this Dharma for even the space of a single meal: their merits surpass that beyond comparison.]
[Commentary:] This is the benefit of the wisdom gained through thinking. Although the ten good actions are many, they are defiled karma of humans and gods. Although thinking and cultivating [this Dharma] may be brief, it is the undefiled cause of buddhahood. Therefore, it surpasses the former beyond comparison.
