The 1st chakra, at the base of the spine, centers on primal instinct, sexuality, and survival. It relates to our sense of connectivity to Gaia, of being grounded, as the roots of a tree, to nature and our source. The earthy red color signifies strength, fortitude, and confidence as well as anger and aggression if in defense of self-and-species preservation. The muladhara teaches us about trust, autonomy, and mindfulness. It is the seat of enthusiasm and passion.
