One thing I've yet to touch on yet although I use it regularly is sound therapy. Sound has been used as a healing tool for centuries and sound therapy has been very useful in my own heart chakra balancing lately. My favorite for of meditation and sound therapy is drumming. Drumming actually opened me up to experience my very first meditation.
Each chakra has a sound that correlates to it and for the heart chakra that sound is 'yam'. You can listen to a repetitive recorded sound or chant it to resonate with you heart chakra. Sound therapy deserves an entire blog series by itself but I wanted to share with you a recording that I use often for my own meditation. When I feel distressed just playing this helps me focus.
