We find the spectrum of the Berezin operator T on L(Bn), then we show that if fL(Bn) satisfies Sf = rf for some r in the unit circle, where S is any convex combination of the iterations of T, then f is M-harmonic.

Finally we decompose the subspace of L(Bn) where lim Tkf exists into the direct sum of two subspaces of L(Bn).
