Meditate Not to Meditate (Milarepa)

Moreover, to meditate is an illusory thought;
Not to meditate is illusory, too.
It is the same whether or not you meditate.

-- Milarepa

Nobody's World (Trungpa)

In relating with the world, there are some very tough questions. What is the world? Whose world is it? What does relating mean? The basic point is that this is nobody's world, since there is nobody as such. The energy constantly taking place does not belong to anybody but is a natural organic process.

-- Chogyam Trungpa, from True Perception: The Path of Dharma Art.

The Middle Way (Aryadeva)

Not existence and not nonexistence
Not these two conjoined nor the opposite of this
Freed from four extremes, the truly wise
Are those who keep within the middle way.

-- Aryadeva

Phenomena Unarising (Nagarjuna)

Neither from themselves,
Nor from another cause,
Not from both,
Nor yet without a cause:
Phenomena indeed of any kind are never born.

-- Nagarjuna, from the Mulamadhyamaka-karika (Foundation of the Middle Way)
