## Chapter 46: Description of the Six Categories and Five Astikayas
**Verse 11:**
**Time Commentary:**
Neither the origin nor the destruction of a substance exists, its existence is real. Its transformations bring about its disappearance, origination, and permanence.
**Commentary:**
Here, the characteristics of a substance are explained through both the substance-oriented and transformation-oriented perspectives.
A substance, which is characterized by the co-existence of qualities and the sequential transformations, and which exists in all three times (past, present, and future), being eternal and without beginning or end, cannot be subject to destruction or creation. However, some of its transformations, which are co-existent, may be permanent, while others, which are sequential, may be subject to destruction and creation. Therefore, when considering a substance in its own right, it should be understood as being without origination and destruction, and having an inherent nature of existence. However, when considering it in terms of its transformations, it should be understood as having origination and destruction.
All this is free from contradiction because there is no difference between a substance and its transformations.
