Here's a recent quote from His Holiness, Sri Sri Ravi Shankar, founder of the Art of Living Foundation.
"Light doesn't fight with darkness. Darkness has no existence, it is just the absence of Light. Even if a room has been dark for 20 years, it doesn't take Light 20 years to get rid of the darkness... Light comes and Darkness is defeated just like that."
We tend to give the negatives of life too much importance and power over us. It is easy to get caught up with this negativity, and fall prey to inaction and apathy. It is a common tendency of the mind to see a glass as half empty, but inaction is a really heavy price to pay.
With wisdom and commitment, we can shift our perception to the reality - that every negative is simply the absence of a corresponding positive. With this attitude, strength and confidence, it is possible to make a genuine difference in the world.
Once we do set our eyes on such a goal, we need a strong foundation in order to face such apparent negativity. It is crucial to empower ourselves with tools and methods to manage our bodies, minds and spirits and navigate the challenges of life.
