般若心經略疏連珠記 1.24

1.24

「大菩提心」者，即直等三心深廣。行者離相為深、隨相為廣，般若具明二行故。

Regarding "the great bodhicitta", it refers to the deep and broad nature of the three minds such as the straightforward mind. For a practitioner, departing from marks is deep, and according with marks is broad, because prajñā fully clarifies both practices.
