What is the use of giving in to sentiments? What for is your self-confidence defeated? Why is your usual calmness of mind disturbed? For what purpose are you desisting from yoga*?
You are a warrior. Make effort to act. Practice meditation to calm your mind. Make the strength of your effort the cause of your success.
*yoga in simple terms means controlling your body (through physical postures) and your mind (through meditation).
[Ramayan Book 4 (Book of Kishkinda), Chapter 30, Verse 16,17]
