Commutative Algebra, chapter X, § 9. Modules dualisants

Let Ω\Omega be a dualizing AA-module; for every projective AA-module LL of rank 1, the AA-module Ω⊗AL\Omega \otimes_A L is dualizing (A, X, p. 108, prop. 7, b)). We shall see below (No. 4, prop. 6) that every dualizing AA-module is isomorphic to a module of this form.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
