Chakra 5, the throat chakra, is the seat of the intuitive self, the divine wisdom. The throat chakra is associated with the creative mind and creativity (compare with the rational mind of the intellect).
When the throat chakra is active, we are communicative, expressive and persuasive, artistic and creative: the wisdom of the soul self is spoken directly, or otherwise communicated. We become proficient in manifesting our vision.
When the throath chakra is clean, we feel an unshakable inner peace: we feel strong, no matter the circumstances - not the strength of power, but the strength from resting in ones higher, or divine self.
