大方廣佛華嚴經隨疏演義鈔 43.65

43.65

疏「復云門者」，即《智論》「問云：何以不但言三昧，而復說門，答：但語三昧無量數，如虛空無邊，菩薩云何盡得？是故說門。」菩薩入一三昧中，攝無量三昧。「如牽衣」下，同此中意。

Regarding the commentary's phrase “Again it is called ‘gate’”: this is from the *Mahāprajñāpāramitopadeśa*: “Question: Why does it not merely say samādhi, but also speaks of ‘gate’? Answer: Merely speaking of samādhis, they are immeasurable in number, boundless like space; how could a bodhisattva attain them all? Therefore it speaks of ‘gate’.” When a bodhisattva enters one samādhi, it subsumes immeasurable samādhis. Below, “like pulling a garment” shares this intention.
