The Yoga of Action (YS 2.1) has two purposes: 1) cultivating steady attention or moving towards complete absorption and 2) minimizing suffering.
In other words, the practice of yoga has two benefits: it reduces suffering and clears perception. As we practice the yoga of action, the right action becomes automatic. Gradually, we move in the state of attention (samadhi) and our suffering is reduced. In fact, we are all capable of clear perception. But somethings come on the way. The following sutras address possible causes of suffering.
