It is more a question of being in balance or not, rather than about being open or not. The more in balance you can be with having you energy open, then that is perfect; because having an open energy simply means broadcasting yourself. Can you be too much you? Not really. Can you be too much out of balance, and thus in disagreement with what you broadcast? Maybe. Also, in my tantra, what is known as the chakras are simply wisdoms of your body. If you feel a danger in being too wise... then do not open up that treasure chest some call chakras
