大毘盧遮那成佛經疏 2.59

2.59

第三十「云何迦樓羅心？謂隨順朋黨羽翼法」者，此鳥常恃兩翅挾輔其身，所往隨意以成大勢，假少一羽則無所能為。此心亦爾，常念多得朋黨與輔翼相資以成事業。又因他所作而後發心，不能獨進。如見人行善，便念：「彼尚能行，我何不為？」當念勇健菩提心，如師子王不籍助伴，為所對治。

The thirtieth: "What is the garuḍa mind? It is following the way of relying on companions and wings." This bird always relies on its two wings supporting its body to fly at will and achieve great momentum; if it were missing just one feather, it would be powerless. This mind is also like this: it constantly thinks of gathering many companions and wings to assist one another in accomplishing tasks. Furthermore, it generates the aspiration only following what others do, unable to advance alone. For instance, seeing another person doing good, it thinks: "If that person can do it, why should I not?" Recollecting the courageous bodhicitta—like a lion king who relies on no companions—serves as its antidote.
