Eknath Easwaran's Commentary
A tremendous amount of our vital energy is squandered in the vacillations of the mind. If things go our way, we get elated; if things do not go our way, we get depressed. Yet elation and depression are made from the same cloth.
It is when the mind is getting elated that we need to be very vigilant, because what goes up will inevitably come down. If, through the practice of meditation and repetition of the mantram, we can keep the mind calm when good things are coming our way, then when bad things come, we won’t be dejected. Our mind will stay calm.
Only then will we be free to be truly spontaneous in our responses to life.
