Ajna is the third eye Chakra. The inner eye is our intuition and gives us our ability to obtain wisdom that cannot be received through the physical senses. When it is blocked we may feel untrusting, cynical, and attached to logic. When Ajna is open and flowing we will have a trust and confidence in our own innate wisdom, and be able to make clear decisions and deal more smoothly with the turbulence and challenges of life.
Ajna governs the functioning of all the other chakras. Blue Sapphire is the stone of mental and psychic activation, increasing extrasensory perception and helping us to see our inner wisdom. Blue Sapphire works on Ajna but also activates Vishuddha, and the combination of insight and clear communication is a powerful one.
