With the mind harboring love and hatred,
and thoughts carrying flattery and crookedness,
one is full of confusion and perplexity,
and cannot enter the citadel of enlightenment.
To return to the realm of enlightenment,
desire, anger, and delusion must first be eliminated.
When attachment to the dharma [of nirvana]
no longer exists in the mind,
one can gradually reach accomplishment.
from The Sutra of Complete Enlightenment, p. 53
