When you walk on a path... you'll need something or someone to guide you through. Some people take shelter in religious ways, some in spirituality, some in this universe and some in particular being. You ask anyone, they will have their individual theories and views. But the beauty of these believes is TRUST! You feel liberated by following something or someone. That is the key which can take you upwards. There is a need to train your brain to think positive and grateful in each and every situation of your life. It's really difficult but not impossible. Your trust should be so strong, that what come may your faith is not distorted. Believe me, it's very hard to not divert your faith or be stable in your trust. There will always be situations, in which you question everything but just "let it be" and keep going. That is when you attain everything!
