By looking in a mirror, one perceives his own identity;
But that identity was already there.
In the same way, relative knowledge gives the understanding
Of the identity of the world and the Self -
But it is like using a knife
To cut another knife.
Fire, in the process of annihilating camphor,
Annihilates itself as well;
This is exactly what happens to knowledge
In the process of destroying ignorance.
The cresting of a wave is but its fall;
The flash of a bolt of lightning
Is but its fading.
Drinking up the water of ignorance,
Grows so large
That it completely annihilates itself.
This absolute Knowledge is like
The intrinsic fullness of the moon,
Which is unaffected
By its apparent waxing and waning.
