Think of this: Effort can put food into your mouth, it cannot produce an appetite; it can keep you in bed, it cannot produce sleep; it can make you reveal a secret to another but it cannot produce trust; it can force you to pay a compliment, it cannot produce genuine admiration; effort can perform acts of service, it is powerless to produce love or holiness. All you can achieve by your effort is repression, not genuine change and growth. Change is only brought about by awareness and understanding. Understand your unhappiness and it will disappear—what results is the state of happiness.
