Algebra, VIII, p. 379, § 20. Linear Representations of Algebras

Let E be a left A-submodule of A∗A^*. Let ε\varepsilon be the linear form y↦y(1)y\mapsto y(1) on E. For every xx in E, we have x=cE(x,ε)x=c_E(x, \varepsilon ), so E is an A-submodule of ΘE(A)\Theta_E(A).

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
