The mind is at the root of most of our issues and problems, especially low self-esteem. Whenever you attempt to move forward in your life, it is the mind that sends the message of critical, judgmental and self-destructive thoughts.
You are not your thoughts so no need to be afraid of upsetting your own mind.
Daily meditation gives you a chance to witness how your mind pulls you here and there during your daily activities and in order to develop a relationship with your mind is becoming a witness to your thoughts and refusing to react or act until you are clear.
Trust. You have been given your own inner authority, your own inner compass that is guiding you through time and space.
