The world is a reflection of your dominant beliefs. If you constantly focus on and complain about your problems, struggles and worries, you will perpetuate the same circumstances over and over again. If you start to shift your focus towards the more positive aspects of your life and all of the things that could go right, you will immediately start to experience more good fortune and positive outcomes.
Spirituality is personal. The desire for one person (or group) to impose her (or their) beliefs on others is the source of much of this world’s strife. Believe what you want, and let others do the same. “There is no need for temples, no need for complicated philosophies. My brain and heart are my temples; my philosophy is kindness.” — the Dalai Lama
