TWO WAYS OF QUESTIONING

There are two ways of questioning yourself - your actions, your feelings, your decisions, your thoughts, your state of being. The one is self-inquiry and the second one self-doubt. These two are not at all the same thing although they might at times be confused in moments where you are not clear in yourself. Self-inquiry is motivated by unprejudiced curiosity and an eagerness to learn more about yourself and to better understand your actions/thoughts/feelings. Its basis is a certain amount of self-acceptance and love, which are  giving you a safe place to start from even though your self-inquiry might be causing you to feel temporarily uncertain, restless, doubtful of yourself. Although it is the Ego which is initiating this self-scrutiny, its aim lies beyond the Ego's self-imposed restrictions. Self-inquiry is aiming at bringing more clarity into your mind. In self-inquiry the Ego is showing willing to face and to overcome its current personal limitations. Hence the answers you find to your self-questioning are representing opportunities for personal growth and self-enlightenment.
When doubting yourself, on the other hand, it is the Ego's fears which are at work. Self-doubts arise from the presumption that the way your are must be wrong/insufficient in some way. It is the fear-beset Ego putting itself in question and because its motivation is fear in the first place, of course, the answers you are arriving at are not assuaging your fears but are actually enhancing them still further. So that afterwards you are not experiencing more clarity but quite the opposite. Therefore, if you have a lot of fear in you but harbour the desire to inquire into yourself and to grow out of your fears it is advisable to first cultivate love and acceptance towards yourself and your way of being - including your fears - because this will give your Ego a safe ground to set out from.
