All progression is in the relative world. The human form is the highest and man the greatest being, because here and now we can get rid of the relative world entirely, can actually attain freedom, and this is the goal. Not only we can, but some have reached perfection; so no matter what finer bodies come, they could only be on the relative plane and could do no more than we, for to attain freedom is all that can be done.
