Algebra, VIII, p. 55, § 4. Semisimple Modules

If A is a field, then every A-module is semisimple by Theorem 1 of II, §7, No. 1, p. 292. This shows that, in general, a semisimple module decomposes in several ways into a direct sum of simple submodules (see, however, Corollary 2 of VIII, p. 68).

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.
