In this doctrine, the consciousness of one living being never really comes to an end. Rather, with each rebirth, one’s consciousness does not start completely new instead builds on previous lives.
To this school, the external world has no permanence, as our consciousness is always changing. So nothing can exist independently of the mind.
This is not to say that the whole world is the result of only one consciousness. Rather the world is the result of the consciousness of each person put together.
The affect of our karmic actions is said to “perfume” or contribute to the conditioning of our consciousness.
