Question: Are relationships (parent-child, spouses, siblings, friends etc.) also emptiness?
Answer: Emptiness means being subject to change and thus being empty of any fixed nature. If so, indeed, relationships are of the nature of emptiness, as people change physically and mentally. But this does not mean relationships are nothingness or meaningless, as relationships are still there and we still need to relate to one another responsibly.
The changeable nature of relationships reminds us that we should diligently change them to be better and better, as we learn to relate to one another with greater compassion and wisdom. This makes all relationships meaningful. The very word ‘relationship’ means ‘a way of relating’. When we note the changes in a relationship, we learn to skilfully change in the way we relate too.
