Unless one sees the Buddha in oneуs mind, Nirvana is obscured.
Although the Wisdom of Nirvana and the Ignorance of the Samsara illusorily
appear to be two things, they cannot truly be differentiated.
It is an error to conceive them otherwise than as one.
Erring and non-erring are, intrinsically, also a unity.
By not taking the mind to be naturally a duality, and allowing it,
as the primordial consciousness, to abide in its own place, beings
attain deliverance.
The error of doing otherwise than this arises not from Ignorance in
the mind itself, but from not having sought to know the Thatness.
Seek within thine own self-illuminated, self-originated mind whence,
firstly, all such concepts arise, secondly, where they exist, and,
lastly, whither they vanish.
(The Yoga of Knowing the Mind, the Seeing of Reality,
Called Self-Liberation)
