In the Tathagatagarbha sutra, Buddha nature is portrayed figuratively as a little Buddha inside each sentient being. Each being is a womb for the Buddha.
An ignorant or self centred person might imagine that through practice they would actualise a personal Buddha.
Except, the Buddha which is represented in each sentient being is the same Buddha. These same buddhas form a kind of fabric, containing all beings, like a womb. Each being is like the embryo in this womb of Buddha.
It is like space: in this moment, is the breath inside you yours, or not?
Is the dynamic space inside you as the expression of this breath yours, or not? How can we distinguish this inner space from the greater space which holds us?
Yet if Being collapses, space likewise collapses.
All these little tiles create the vast space of the temple.
