The reason why it’s so important to keep your chakras open with energy smoothly flowing through them is when they're closed or imbalanced it can lead to illness and/or emotional instability.
A main way to tell if your chakras are open or blocked is to pay attention and be aware of how you feel. When your chakras are open you'll have energy and feel happy and light. When they're blocked or unbalanced you'll feel heavy, exhausted and out of sorts, like something is wrong.
Basically the trick to opening your chakras is this, simply clear out negative (depressed) energy. And get yourself in a feel-good space again.
Something important to know about your chakras is they are energy that's in constant motion. Which means you can't go to someone and get your chakras balanced one time and think you're good to go for months. You could walk out the door feeling AMAZING and then get in a horrific wreck (or witness one etc.) on your way home.... and I guarantee you your chakras won't be balanced and open anymore. No matter how open and balanced you were an hour ago you're going to feel stressed and your energy is going to be totally out of whack!
Things you can do to keep yourself energetically clear include heartfelt prayer, meditation, visualization, yoga, saying declarations (affirmations), doing anything that releases negative emotion, eating real organic plant foods, drinking plenty of pure water, and using pure essential oils. Essential oils, as long as they're truly high quality and pure and not synthetic, are especially powerful because they have super high frequencies that chakras immediately respond to.
