金剛般若經贊述 1.104

1.104

今此一唱名廣大心者，謂十方無邊、世界無邊、眾生無邊，如是無邊眾生，我無始來於彼起於十惡，今發心已，於此眾生皆擬濟拔攝受，故名廣大心也，竝欲度脫故。

Now, this proclamation is called the 'vast mind' because the ten directions are boundless, the worlds are boundless, and sentient beings are boundless; toward such boundless sentient beings, from beginningless time I have committed the ten unwholesome deeds toward them, but now having generated the mind, I intend to deliver and gather in all these sentient beings, and therefore it is called the 'vast mind', because one wishes to liberate them all.
