You can't make radical changes in the pattern of your life until you begin to see yourself exactly as you are now. As soon as you do that, changes flow naturally. You don't have to force or struggle or obey rules dictated to you by some authority. You just change. It is automatic. But arriving at the initial insight is quite a task. You've got to see who you are and how you are, without illusion, judgement or resistance of any kind. You've got to see your own place in society and your function as a social being. You've got to see your duties and obligations to your fellow human beings, and above all, your responsibility to yourself as an individual living with other individuals. And you've got to see all of that clearly and as a unit, a single gestalt of interrelationship. It sounds complex, but it often occurs in a single instant. Mental culture through meditation is without rival in helping you achieve this sort of understanding and serene happiness.
Remember, we all want to be happy and meditation is the way actually to accomplish this.
