Santideva's non-self argument, as outlined in Chapter 10, suggests that since Buddhism teaches the doctrine of no-self (anatta), the distinction between one's own suffering and the suffering of others is essentially arbitrary. Therefore, all suffering should be of equal concern, as the concept of "your" suffering is undermined by the understanding that there is no enduring self to which suffering can belong.
