大毘盧遮那經供養次第法疏 2.4

2.4

初、釋名者，行者供養合聖海，聖海歡喜受。初供一供，種種供養滿聖海，故言〈供養儀式品〉。所謂供養有三：一者外供養，謂香華飲食及燃燈，莊嚴道場等也；二者行供養，謂如說奉行及禮拜持戒等也；三者理供養，謂心住法體，無外攀緣也。

First, explaining the title: when the practitioner makes offerings, they accord with the ocean of noble ones, and the ocean of noble ones joyfully receives them. Making a single initial offering, diverse offerings fill the ocean of noble ones; hence it is called the 'Chapter on the Ritual of Offering.' The so-called offerings are of three kinds: first, external offerings, namely incense, flowers, food and drink, lighting lamps, adorning the bodhimaṇḍa, and the like; second, offerings of practice, namely practicing as taught, prostrating, keeping the precepts, and the like; third, offering in principle, namely the mind abiding in the essence of dharmas, devoid of external ālambana.
