Even though your chakras may be cleansed and shining brightly there is still the possibility of imbalance. One too strong, another too weak. A good way to balance out the chakras is to use crystals and meditation in combination. If when you visualize your chakras some appear dull (even though cleansed) and some excessively bright then you would benefit from balancing them.
To do this select the crystals necessary for strengthening (or weakening) the relevant chakra (see list below). Lie down and place the crystal on each chakra deemed necessary. Breathe in and imagine your breath moving throughout your entire body and exiting through the soles of your feet, picking up the energies of the crystal(s) along the way. Some people find it helpful to make an affirmation for a particular chakras such as "I will give and receive unconditional love" for the heart chakra
