The essence, form, and function of the mind 心之體相用

The mind has its essence, its form, and its function. To understand its function is to understand karma and causality. To understand its form is to understand emptiness. To understand its essence is to realize the pure awareness that is neither created nor perishable. To be enlightened to the mind's essence, form, and function is to know the bodhi mind.

心有體、相、用。悟到心之用即是了達因果。悟到心之相即是了達空性。悟到心之體即是了達不生滅的覺性。體相用全部悟到了即是菩提心。
