攝大毘盧遮那成佛神變加持經入蓮華胎藏海會悲生曼荼攞廣大念誦儀軌供養方便會 2.19

2.19

定慧內成拳，火空各竪合，
風屈持於火，形由似寶珠，
此印摩訶印，所謂如來頂，
適纔結作之，即同於世尊。

Form inner fists with samādhi and prajñā; erect and join fire and space together;
Bend the winds to hold the fires, shaped like a precious jewel.
This mudrā is the mahāmudrā, namely the Tathāgata-Uṣṇīṣa;
The moment one forms it, one is identical to the World-Honoured One.
