There is only one teaching, that is, the One Vehicle
In the Buddha-worlds of the ten quarters.
There is not a second or a third vehicle
Except when the Buddhas teach expediently.
The Buddhas lead all living beings
By tentative names [of vehicles]
In order to expound their wisdom.
They appear in the worlds
Only for the One Vehicle.
