Sillimanite is about change, but it is about the end results of change and the completion of a project or task. Unlike many other crystals which encourage one to make planned changes in one's practise or mode of life, sillimanite gives support for the home stretch. It helps remind one that the goal is close and the work nearly done. It provides the final burst of energy to finish the last few tasks that are required. It protects against burn out and helps ward off fear of completion.
