Actually, not. Discepleofthegods, many people here have done the opening the soul meditations. Yet, I can feel many people who still have their chakra closed. Particularly the third eye and consequently the sixth chakra.
When your third eye is open, you can see through any lie and see energy all the time around you, effortlessly. How many people can do that here? I bet they can be counted on the tips of your fingers.
Opening chakras is an individual process. Everyone, when approaching SS for the first time, is at a different stage of spiritual advancement.
Sure those meditations are helpful, but it's individual how long it takes for you chakra to open. It can take one day for you, it can take several months of working for the stud next door.
