All dharmas that arise from causes and conditions,
I call them emptiness.
They are also provisional names,
And also the Middle Way.

── from Mulamadhyamaka Karika
(Treatise on the Middle way)

Dharmas are inherently empty of nature,
Neither arising nor ceasing;
Originally quiescent,
Nirvana is one’s nature.

── from Mahaprajnaparamita Upadesa
(Treatise on the Great Perfection of Wisdom)

All phenomena are impermanent,
All dharmas are non-self,
Nirvana is perfect tranquility,
Such are the Three Dharma Seals.

── from Mulasarvastivada Vinaya
(Original Monastic Code of the Sarvastivada School)

All phenomena arise from causes and conditions,
All phenomena cease by causes and conditions.
Our Buddha, the great Sramana,
Always speaks in this way.

── from Siksasamuccaya
(Compendium of Buddhist Doctrine)
