Why should we think upon things that are lovely? Because thinking determines life. It is a common habit to blame life upon the environment. Environment modifies life but does not govern life. The soul is stronger than its surroundings.
You are today where your thoughts have brought you; you will be tomorrow where your thoughts take you.
You become what you think about.
You live with your thoughts — so be careful what they are.
You need not aspire for or get any new state. Get rid of your present thoughts, that is all.
