說無垢稱經疏 2.88

2.88

贊曰：常修妙行莊嚴佛土，名為嚴土。觀無為法，不離心首，如以金為髻，故名金髻。常以智慧嚴飾其心，如以珠為髻，故名珠髻。或一乘者佛髻明珠，菩薩常修，故名珠髻。

Commentary: Constantly cultivating wondrous practices to adorn the Buddha lands is called 'Adorner of Lands' (Kṣetrālaṃkāra). Contemplating unconditioned dharmas without departing from the crest of the mind, like having a topknot made of gold, is why he is named 'Golden Topknot' (Suvarṇacūḍa). Constantly adorning his mind with wisdom, like having a topknot made of jewels, is why he is named 'Jeweled Topknot' (Maṇicūḍa). Alternatively, the One Vehicle is the bright jewel in the Buddha's topknot; the Bodhisattva constantly cultivates it, hence he is called 'Jeweled Topknot'.
