You go through many layers of mental experiences, trying to overcome the negative expressions of the personality, the conflicting thoughts, the feelings of insecurity, loss, connecting with the source of inner strength, developing a relaxed state, developing a focused state of mind.
Just as you identify with the world and attach yourself, there is also an internal identification with the inner self. Just as you feel threatened and in secure when something external is shaking your connection, there is also in security when something happens internally and it changes your life, your mind and your attitude.
When you become natural, when there is no imposed projection of an image, when you are able to guide and control the energies in motion within you, you are able to cultivate the positive, optimistic and qualitative form of life. Confidence is knowledge, understanding and awareness of your strengths and ability to deal with a situation. When you know you are the master of the circumstance or event and can control it, and you have the wisdom to know what is right and wrong and act according to dharma, that is confidence.
