大日經略攝念誦隨行法 1.8

1.8

Samādhi and space [the left thumb and fingers] hold the earth and water fingers,
while wind and fire stand erect at the heart;
the wisdom sword [on the right hand] is formed likewise,
and unsheathed it can accomplish the rites.
Next, the Tathāgata Hook is described,
used to summon the tutelary deity (yidam);
the lords of all the holy hosts
arrive in accordance with their original vows.
