# Go: TerraformSelf

> CDKTN Core API Reference for TerraformSelf in Go.

Expressions in connection blocks cannot refer to their parent resource by name.

References create dependencies, and referring to a resource by name within its own block would create a dependency cycle.
Instead, expressions can use the self object, which represents the connection's parent resource and has all of that resource's attributes.
For example, use self.public\_ip to reference an aws\_instance's public\_ip attribute.
