Perumal recognizes all matters through his swaroopam and sankalpam. He controls certain matters physically and certain others by his will.
For example, by his divine will he makes the planets remain in their orbit, stars are at their positions, and the sea is within its limits. These are known as sankalpena dharakatvam; he supports them through his will. Swami Desikan has mentioned in Srimadrahasyatrayasaram that there are two kinds of dharakams.
