When a chakra is really open so you obtain powers siddhis. Until you do not have any siddhi power so you have none chakra open. But, take it many years meditations on a one chakra only. For example swami Raghavanand said that nobody can open all chakras in one life.
There are two different paths with chakras on the East.
1/Cleen all chakras and wake up the Serpent power - kundalini - for the end cycles of lives.
2/Open a chakra for obtain supernatural powers and better life.
First path is in books like Shiva samhita, Gheranda samhita, The serpent power - translantion by Arthur Avalon (John Woodroffe).
Second paths is in book The secret of the golden flower (Chinese taoists spiritual alchemy), translantion by Richard Willhelm. But there is chakra Ajna called a "heavenly heart" and chakra Anahata a "fleshly heart".
