When you do the sun salutations with your mind still attached to the mundane world, you get a good calesthetic workout.
When you do the sun salutations with your mind focused on your breath you begin to surpass the limit of this material body.
When you do the sun salutations with your mind fixed on your breath and the divine within you, you are in union with the Cosmic Energy.
When you do EVERYTHING in life with your mind fixed on breath and the divine, you attain bliss!
The mind is our worse enemy and our best friend. “To control the mind is like trying to grasp the wind in your hands,” as said in The Bhagavad Gita.
But the Yoga Sutra says one can attain the goal of yoga through Dispassion (Vairagya) and Practice (Abhyasa), which means mental detachment and sincere and persistent practice. This is why we need to practice.
