Oh, yes you would! There are several ways you can do this. These are the most two simple ways:
1.
Take a 1 minute iced shower and wash your head fully, don't worry about the shock (unless you suffer from an underlying condition such as a heart problem - if you do, don't take cold showers). It is the equivalent to hundreds of milligrams of caffeine and it pours open all your chakras after the shower. After 30 days of doing this, you might even feel electric shocks going through your body from all the open chakras.
2.
Take a hot shower, pause for 1 minute to bathe yourself in blue soap or blue soap gel and wash yourself fully all over your body with the blue soap. Wait 30 seconds-1 minute before turning on the water again and clean your body.
Taking cool showers does have some health benefits, particularly towards metabolism. And running water is an energetic cleansing as it helps ground away energies you consciously release. I have heard some say that it sort-of 'retracts' the aura closer to the body and pulls negative energy off like washing dirt off your skin. Which is usually related to why showers help so much in making you feel more at peace/content and calmer afterwards. A cool shower works week as a calming/stress-relieving action.
However, while it is cleansing it takes more than running water and a bit of color to achieve things like fully open/active chakras and spiritual connection. It is a small component of Self care that can assist in such a journey, but it is just that. One small factor.
Getting back to comparing open chakras and spiritual awareness... I agree that the two are co-related. Working to open and empower the chakras and working to grow in your connection to Self (and 'the universe') involves a lot of the same things. And, generally, advancing your journey with one involves practice with the other. For example, actively working with your chakras through meditation is begun by learning to be aware of (and in tune with) your energy and it's flow.
I wouldn't say that having someone's chakras opened would by-default mean that person would be 'in tune'. There is nothing to say that this person has learned how to listen. Or what it even means to be in tune. Or how to gain from it in a useful or practical way.
This is one reason why these things become a journey in the first place. Because learning how to do it gives way under trying to understand what it means for your growth as a person. Things like 'opening the chakras' and 'tuning in to the universe' don't make a person spiritual... Rather, learning to be spiritual and applying it is what leads to achieving these things.
Like Spirit76 said, you don't need to have all your chakras open to be more in tune with the Universe. You would be more in tune and yes it does take more than blue soap to open your chakras - but water is the main source of survival and used in countless religions, doctrines all over the World to channel their energy, but you also need to meditate and take care of your health in a significant manner such as eating healthy, drinking water, quitting all processed food and harmful medications. This includes marijuana (marihuana, weed, whatever you want to call it) due to the fact that if you're fully awakened and in 5D your cognitive system and CNS will produce these chemicals in your brain without the need to smoke them.
Going back to your chakras, cold showers help open them if you take cold showers everyday, the shock you feel when you take a cold shower is due to the chemical imbalance in your brain and in your CNS and after you stop feeling the shock you will then know your chakras are starting to pour open. But like I said, it only helps, you need to put in the other side of the work. You also need to sleep. You can replace meditation with sleep if you're in the 5th Dimension and 10 minutes do not replace 4 hours of sleep, each minute of meditation resubstitutes a certain amount you need to sleep and if you meditate for 7 hours, per example, you would only need to sleep for 1 or 2 hours - like Sidartha Gautama (also known as Buddha) did. This is a great way of balancing your chakras also. Meditating for long hours and sleeping little. But remember that meditation cannot fully replace sleep, so sleep aswell. Sleep is vital and essential when it comes to opening your chakras. Buddha spent nights meditating and sleeping only 1 hour to refresh himself as meditation cannot fully replace sleep. And he was alligned and fully awakened, describing "individualism is what is separating us" - which implies, he's refering to being one and only with the Universe and being in tune with God and BEING God. You can choose wicca if you want and not believe in God, but you can be your own God even praticing wicca and being a wiccan. I dated a wiccan that also believed in God - which taught me a lot, about, forgetting the dogmatic patterns the political and religious system has imposed on us - being limited spiritually. You can believe in whatever you want, someone can tell you you're wrong but that's just their opinion or judgement - only you can decide what to believe in. Don't let someone think for your beliefs. That's also apart of becoming more in tune with the Universe.
About being more in tune with the Universe, astral projection also helps. I astral project everyday as I believe I'm in 5D - but I'm unsure, I have doubts. I also met a friend of mine a few years back that said he had doubts about being awakened. When you fully doubt yourself spiritually and dispose of all dogmas, you will be more in tune with the Universe but remember to believe in your dreams and pursue what you love. There's this saying most people die after 25 - which is not my case. I pursued my dreams and did work in what I loved the most and still do - music.
Hope this helps you along with the message from Spirit.
