Mind is the creator of everything. You should therefore guide it to create only good. If you cling to a certain thought with dynamic will power, it finally assumes a tangible outward form. When you are able to employ your will always for constructive purposes, you become the controller of your destiny.

Paramahansa YoganandaBuild your inner environment. Practice Silence! I remember the wonderful discipline of the Great Ones. When we used to talk and chatter, they would say: "Go back into your inner castle." It was very hard to comprehend then, but now I understand the way of peace
