that article was really helpful for me. if i were you, i'd incorporate balancing your chakra's into your daily meditation [if you have a meditation schedule, it's helpful] start at your root and work your way to the crown. personally, i started with one chakra a day, so i could focus all my energy on that one chakra, get to know it, and throughout the day try to see if anything was different with the chakra open. [takes a week] once i've done that with each chakra, i'd balance two starting from the root to the crown, then so on until i can balance all seven in one sitting. [takes about a month]
don't get discouraged, it takes a while to get good with meditation and chakra's. also, there's many different methods to visualize your chakra's. spend the first month playing around with your visualization of them. as long as their the correct colour, it doesn't matter if you visualize a flower, a disk, a gemstone, a cat, a pearl, a dragon, whatever, it just needs to be the corresponding colour really.
