The Sodalite stone is said to encourage being true to Self and standing up for your beliefs. Believed to be a stone of self-expression and confidence, Sodalite can aid in issues of self-worth, self-acceptance, and self-esteem. The stone is also said to promote intuition and a trust in one's own judgment. Indeed, many a Wizard has used the stone to help them better trust in themselves, which is after all, one of the sorurces of the Wizard's power.
In addition to these things, Sodalite is thought to help in achieving emotional balance, and releasing old habits of the past which no longer help to serve.
