I've experienced both of these states of mind today. Though the two ways of being might seem incompatible, they actually blend like milk and honey. In yoga and life you have to have both to see you though the difficult times and to build the endurance you need to stay on track. Today I lost my focus and my balance and I had to remember how important is to combine serenity with your will-power. A strong sense of calm goes a long way towards tempering your drive and making the goals at the end of a particular journey that much sweeter once attained. Not only is your prize hard-won, but it is also there to stay.
