If introspection is practiced on a daily basis before retiring, then you can pull your life together fairly quickly by becoming aware of the things that do not work in your life. Whitewash your day, going backwards over the events from evening to morning and become aware of any circumstance that needs to be changed to make your life work better for you.
You will find that after a while of practicing this method, your life will take on a different quality of depth and inner peace. Daily examining your experiences, the decisions that you make, the relationships you have, and the things you engage in, provide useful insights into your life goals, and if you are on the right track to realising them. If you become aware of any negative trait that keeps reappearing, make an effort to transmute it into the opposite polarity.
Introspection will also give you clues on how to act, how to respond to others better, and how to conduct yourself in the midst of any situation. Like any skill, introspection can be learned; all it takes is a little daily practice. It is a good idea to make notes in a journal so that you can monitor your progress. Remember to be forgiving of yourself if you find a trait difficult to remove. Continue to focus on the positives to assist your overall improvement.
It is a good thing to remember that you are a spiritual being that has taken on a personality so that you may have experiences in the earth plane phase of your existence. Your experience should include ennobling your personality through honest and dedicated daily living, so that your soul may infuse your personality with higher vibrations until you experience yourself as a soul personality. Introspection, of course, is only one way of becoming aware of those things that hinder your personal growth.
At some point during your life, you will search for the meaning of your existence. This will normally mean that you will move out of your comfort zone and begin a more spiritual search for meaning. You may become aware of the four temperaments that influence all human behaviour—choleric, sanguine, melancholic and phlegmatic. These temperaments are related to the original elemental principles of fire, air, water, and earth that underlie all existence. They have proceeded from Akasha or the Etheric Principle, which is sometimes regarded as the fifth power, or original power. So, even in the Godhead, we can see these principles demonstrated in the divine qualities of omnipotence, omniscience, omnipresence and omniawareness.
As your consciousness begins to expand, you will come into a greater awareness and appreciation of all forms of life and begin to realise that the material plane is merely a crystallisation of spiritual form that has been stepped down in frequency through the process of the principle of sub-harmonics. We are all just unique individual notes of the vast symphony of life that is constantly playing in the universe. So, practice introspection daily to remain aware and tune into the hidden potentiality of your Soul.
