大日經持誦次第儀軌 1.167

1.167

此中訶字門，聲理如前說，
少分差別者，所謂淨除相。
降伏三界尊，身密之儀式，
當用成事業，五智金剛印。

The syllable HA-dvāra here,
its sound and principle are as explained before;
its slight distinction
is the aspect of purifying and removing.
For the bodily secret ritual
of the Lord who Subdues the Three Realms,
one should use to accomplish the karma
the five-wisdom vajra-mudrā.
