You can't understand the 10 bhumis merely by reading their names. Perhaps even reading their descriptions doesn't help either. Nor can you understand them out of order, because each one supports the next. They may seem like stupid poetry.
A stupid person might ask:
-Is the first bhumi the only one which is joyous?
-Is the second bhumi the only one which is free from defilement?
-Is the third bhumi the only one which is luminous?
-Is the fourth bhumi the only one which is radiant?
etc..
But you have to understand the jhanas first in order to understand the bhumis. And the bhumis can't be understood out of order, so you have to understand the first bhumi, the joyous, for any of them to make sense.
Perhaps confusion arises from thinking of the ten bhumis as ten different people, and from an ordinary perception, they might all appear to be simply holy people. The confusion arises from thinking of the bhumis as applied to things outside of your mind. Instead, see the bhumis -- the transition from bodhisattva to Buddhahood -- in your own mind, as your own practice of meditation, and it's beautifully simple.
Does what I said above make sense?
