Your mind will sometimes shudder when evil thoughts enter your mind. This is a sign of your spiritual progress. You are growing spiritually. You will be much tormented when you think of your evil actions committed in the past. This is also a sign of your spiritual upheaval. You will not repeat now the same actions. Your mind will tremble. Your body will quiver whenever a wrong thought of some evil action urges you to do the same act through force of habit. Continue your meditation with full vigour and earnestness. All memories of evil actions, all evil thoughts, all evil promptings of Satan, will die by themselves. You will be established in perfect purity and peace.
