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 2.37

2.37

With the prajñā-fist, extend the water and fire [fingers],
while the wind and earth press down the space wheel.
This is called the Eye Born of Compassion of All Buddhas, the Refuge of the World.
Visualize placing it upon the field of the eyes; the wise one thereby achieves the Buddha-Eye.
