Instead of caging your heart from the truth of suffering- allow it all in- and watch your spiritual heart grow. Its not an easy path, it's the path of the warrior. In Yoga we are warriors of truth, peace, love and light. The truth is things aren't always pretty, easy and light. However it's through the dark times that you build resiliency and learn to appreciate the light. Just like the butterfly who needs to fight it's way out of the chrysalis- the struggle will make you stronger. Keep going.
