Inhale deep patterned breaths and relax completely. See yourself in each encounter and situation of that day. There is much to learn from this work when practiced sincerely. You'll learn to trace your emotions, thoughts and actions to their source. Through this process you'll gradually act less from egoistic motivations and will resolve the storms of your subconsciousness as you gain ever greater control over your emotions and desires.
Introspection is central to any attempt at purifying the present-day personality.
Good thoughts will produce good actions and bad thoughts mill produce bad actions.
