We can accelerate the process by trying, to the best of our ability, to live a good life, helping others and trying not to harm or hinder them. We should not judge others, for they are on their own path working out their own patterns.
We can read uplifting books and keep company with people of good character. The most important thing we can do to accelerate the process of unfoldment is to do our meditation and spiritual practices regularly. If we do our 10% the Divine Purpose of the Universe will do the 90%, but we must do our part and be sincere.
