once you open a chakra will it stay open?
no but you can use it, with out reopen it
A chakra is basically a circular energy motion.
You can clean your carburator, but how long will it spin properly?
Clean them all regularly and keep a spontaneous gist towards life. You be fine.
um... i dont know what the Naruto version of chakra is, but, based on the version i know, Chakra is a life energy force. It's like ki or chi or mana. It's a built up energy that is generated from either a lot of practice or a natural kinship with yourself and whatever art you practice. This can be seen with dancers or very good martial artists.
A chakra as an energy centre; in a living being it is never completely closed--and never completely opened--except as taught by some gurus selling their remedies or techniques. It is true that energy is controlled by your thoughts and beliefs; therefore, please meditate on your energy centres and the answer and your way will be clear for you. Good luck!
As a chakra is a part of your subtle energy system it like the rest of your energy is in a constant state of flux.
Every emotion, thought & action will change the state of any one individual chakra.
So the answer has to be no.
