The four forms of wisdom are the great mirror wisdom of Aksobhya,

the universal wisdom of Ratnaketu, the profound observing wisdom

of Amitabha, and the perfecting wisdom of Amoghasiddhi.

The great mirror wisdom of Aksobhya has evolved from the alayavijnana,

the storehouse of all seeds of consciousness; the universal

wisdom of Ratnaketu, from klista-mano-vijnana, reasoning; the profound

observing wisdom of Amitabha, from the sixth consciousness or

intellect; and the perfecting wisdom of Amoghasiddhi, from the first to

the fifth consciousness or seeing, hearing, smelling, tasting, and touch.

An enlightened practitioner verging on Buddhahood wholly transforms

the eight kinds of consciousness into four forms of wisdom. Such is

the competency uniquely of the Buddha.
