Chakra 3, the solar chakra, located at the solar plexus, is the seat of the intellectual self. The solar chakra is associated with the rational mind and intellect (compare with the creative mind of the intuition).
When this chakra is dominant, we are ruled by the intellect, and the ego-centric rational mind gains control over the emotions and the instincts, but this control is cold, clinical, aloof, and merciless.
When balanced with the higher chakras, the wise and clear-thinking soul mind replaces control with synthesis. We learn to set boundaries and to honor the boundaries of others. We draw forth energy from our own higher self and from the universe, instead of tapping into the energies of those around us.
