The central teaching of the second turning of the wheel of dharma reveals as the true nature of reality, the intrinsic emptiness of all phenomenon. Śūnyatā in Pali, this is called anutpada in Sanskrit and translated into English as having no origin, non-production, not coming into existence or unborn.
As it says in the Prajnaparamita Sutra,
“Form is emptiness; emptiness also is form. Emptiness is no other than form; form is no other than emptiness. In the same way, feeling, perception, formation, and consciousness are emptiness.”
