The seventh chakra resides outside the body at the crown and facilitates a complete union with the Universal Life Force.
Long-term healing for the First Chakra comes from very physical activities.
Chakra foods (juicy, orange-coloured foods like oranges, mangoes & pumpkins) along with aquatic bodywork (Watsu) are really good for the Second Chakra as it is related to the element water.
Visual therapy such as working with yantras along with sunbathing is recommended as the Third Chakra is related to fire.
Hugging is one of the simplest ways to boost and balance heart chakra energy along with breathing exercises (the element related to this Fourth Chakra is air).
Sound healing is the best in the case of the Fifth Chakra; anything from singing to listening to your favorite song will work wonders.
Visualization and meditation works when attempting to heal the Sixth Chakra as it is related to the third eye.
For the Seventh Chakra, meditation and pure, silent, thoughtless openness is the best. Just opening up to the space that we are, with nothing added.
