Svadhisthana (Sacral or Pelvic Chakra)
Element: Water
Color: Orange
Sound: Yam
Life theme:
This chakra corresponds with your reproductive and sexual organs, and represents fluidity, creativity, and fertility. You can take a literal interpretation of this, or associate this chakra with whether or not you feel deserving of a pleasurable, abundant, creative life. When it’s out of balance, you can feel emotionally unstable, guilty, or hard on yourself. When Svadhisthana in balance, you feel creative, positive, and receptive to change—like the ocean and its tides, you’re in the flow.
