Understand this great truth: The happiness that comes from the pleasures of the world is but a minute reflection of the infinite bliss that comes from within your own Self.
An artist paints with focus; the painting becomes complete only through ekagrata (one-pointedness). Similarly, whatever is our goal, we need focus on that to make it complete.
Drop all your regrets of the past and relax. Relaxation will help you acquire more strength and vitality.
We need to focus on our destination. Let the thoughts arising in your mind pass by, like watching scenery through the window of a car. The thoughts cannot affect you if you don't allow them to capture your attention.
Once we develop the attitude that "I am love, the embodiment of love," then we need not wander in search of peace for peace will come in search of us.
