“As for this sparkling awareness, which is called “mind,” even though one says that it exists, it does not actually exist. (On the other hand) as a source, it is the origin of the diversity of all the bliss of Nirvana and all of the sorrow of Samsara. And as for it’s being something desirable; it is cherished alike in the Eleven Vehicles. With respect to its having a name, the various names that are applied to it are inconceivable (in their numbers).
Some call it “the nature of the mind” or “mind itself.”
Some Tirthikas call it by the name Atman or “the Self.”
The Sravakas call it the doctrine of Anatman or “the absence of a self.”
The Chittamatrins call it by the name Chitta or “the Mind.”
Some call it the Prajñāpāramitā or “the Perfection of Wisdom.”
Some call it the name Tathagata-garbha or “the embryo of Buddhahood.”
Some call it by the name Mahamudra or “the Great Symbol.”
Some call it by the name “the Unique Sphere.”
Some call it by the name Dharmadhatu or “the dimension of Reality.”
Some call it by the name Alaya or “the basis of everything.”
And some simply call it by the name “ordinary awareness.””Padmasambhava
