From all the saints: When you have security issues blocking your first chakra (root), clear the block with prayer, meditation and uplifting music. Yoga and chi gong practices also clear the 6th and 7th chakras.
Why do you start at the top chakras?
It works this way. You reconnect to the Divine Source/Love through the meditation/prayer, this allows you to speak from the heart (throat chakra), expand love and compassion (heart chakra), then to align your will with the Highest Good (solar plexus chakra), use your creative talents (2nd chakra) and clear the root chakra so that you feel safe and secure (financially too) in the world.
Singing spiritual-related songs also unblocks chakras.
