Yoga, the way Krishna defines it, is a subtle and sovereign pursuit of the mind and intelligence. The one given to Yoga saadhana never loses sight of his basic spiritual nature. Equally so, he is ever aware of the supremacy of mind over the body and senses; and also, of the superiority of the intelligence over the mind. The inner personality is his constant focus. Its potentials and possibilities are supreme to him. The expansion, depth and loftiness he sets for himself are thus unbounded.
