The principle of dependent origination also applies to the concept of no-self (anatman).[k] The concept of no-self or anatman or emptiness of self is that it is not possible to identify an independent, inherently existing self; that the self only exists in dependence upon causes and conditions. This theory can be broken down as follows:[22]
If you look for the self within the body, you can not find it there, since the body itself is dependent upon its parts.
If you look for the self within the mind, you can not find it there, since the mind can only be said to exist in relation to external objects; therefore the mind is also dependent upon causes and conditions outside of itself.
Hence, since the self can not be said to exist within the body or mind, it is said to be "empty of inherent existence".
Emptiness (sunyata)
Main article: Sunyata
In the Mahayana tradition, the principle of pratītyasamutpāda is said to complement the concept of emptiness (sunyata). It is said that because all things arise in dependence upon causes and conditions, they are empty of inherent existence.[l]
A classic expression of this relationship was provided by the renowned Indian scholar Nagarjuna in the twenty-fourth chapter of his Treatise on the Middle Way; Nagarjuna stated:[24]
- Whatever arises dependently
- Is explained as empty.
- Thus dependent attribution
- Is the middle way.
- Since there is nothing whatever
- That is not dependently existent,
- For that reason there is nothing
- Whatsoever that is not empty.
Geshe Sonam Rinchen explains the above quote as follows: "Here Nagarjuna states the Madhyamika or middle way position. Everything that exists does so dependently and everything that is dependently existent necessarily lacks independent objective existence."[24]
