Well people who are completely focused on the spiritual path will definitely not need any assistance including crystals and I am with you on that. But I do enjoy working with them because of their higher vibrations :-)Definitely dear @funatoz, chakras can be worked upon with meditation and a lot of conscious living. But Crystal work is not only meant for Chakra balancing, though it does work very fine. It aids to speed up the process due to its high sensory attributes. Crystals help to balance and amplify the energies in our space, so not only the Chakras but it works on your overall space. Crystals vibrate at the same frequency as humans or some at even high levels and hence they assist us in combatting the vibrations of all lower energies and blockages within us, they can work to restore our cells and organs to their optimum functioning levels.
