How to findout and resolve it our Karmas in life through yoga practices?

Bhagavad Gita said that nothing that you have done or studied or any effort that you have made will go to waste. It is a chain of lives and you improve your life slowly. To remedy to Karma, you need to understand that this personality, this life is not really the real picture. You have to learn to see the big picture of your soul’s life. It is the history of your soul.

Yoga is a subtle art, to best understand this concept one should acquaint themselves with eight stages of holistic evolution (Ashtanga Yoga; reference from Srimad Bhagavad Gita and Patanjali Yog Sutras). These stages bind you to the pure nature of soul and there is no end to this divine prophecy, it lifts you up, sheds the burden of karma and finally liberates oneself.
