If this cannot be ours ...

Hi

An author of a certain book writes:

We must reason with ourselves, pointing out that there is really nothing in sensuality, that it is the biggest fraud

possible; and that as far as the higher love of the sexes is concerned, if this cannot be ours, then beyond it all are things more important. I'm not sure if this says: then beyond it all ARE things more important OR then beyond it ALL are things more imprtant?

Does it mean: if we cannot attain this higher love then everything else is more important than this love?

Also: should I understand "sensuality" as "eroticism" or something close to it?
