If you substitute "clinging" for "craving" (Burbea's Seeing that Frees expounds on this very clearly) then I think we get a better English interpretation of the material.
If the mind's full of clinging (either in demanding what isn't present or refusing to release what was present but which is now leaving the present) then that mind doesn't have any room left to experience aliveness.
So (to me) the material doesn't suggest asceticism or abandoning the human sensual potential, it reminds that clinging will sneak in and take over the mental cycles, undermining your ability to live to that potential.
