Explaining the Principles of Quantum Mechanics through Yogācāra

Quantum mechanics describes: a stationary particle decays, producing two photons that fly off in opposite directions over extremely great distances; when one photon is measured or touched, the other photon responds accordingly. Why is this?

Because the two photons share the same origin—they come from the same particle. This particle is composed of the four great seeds of a single tathāgatagarbha, and the four great seeds are intimately connected with one another, no matter how far apart they are. In fact, the distance between the two photons is empty space, and empty space is composed of the great element of space. The great element of space fundamentally does not exist; the great element of space has no distance—there is nothing there at all. Thus, between the two photons there is fundamentally no such thing as distance. No matter how far apart they appear in the mundane physical world, in essence they still belong to the same particle and to the same tathāgatagarbha, possessing the same functions and effects. Therefore, when one changes, the other undergoes the same change, because they share the same origin.

As for the material substances of the entire world, they are composed of the four great elements of sentient beings who share collective karma, so of course they are all intimately connected with one another, and it may be that pulling one hair sets a thousand pounds in motion. But this intimacy is far less intimate than the connection between photons from the same particle. Since empty space has no such thing, no such dharma, then is there still time? In truth, if each of us strives a little harder and exerts a little more strength, we would reach the very depths of emptiness. Why is it that this strength just cannot be exerted? And when will we be able to exert it?
