The sun planet is described as the eyes of all other planets. Yac-cakṣur eṣa savitā sakala-grahāṇām. That's a fact. Unless there is sunrise, you cannot see. You may be very proud of your seeing, "Oh, I want to see," but we do not know that our seeing power is limited and conditioned. Unless there is sunrise, these eyes are useless. Just like at the present moment, at night, we cannot see even four yards. So what is the value of these eyes? It is conditional. If there is sunrise, then we can see. That condition is made by God.
Therefore in the Upaniṣad it is said: "When God sees, you can see. When God walks, you can walk." These are the description in the Upaniṣad. Practically, that is the fact. We are completely helpless, simply dependent upon God. The word that, "Not a single blade of grass moves without the sanction of God," that's a fact. In the Bhagavad-gītā also it is said, sarvasya cāhaṁ hṛdi sanniviṣṭaḥ: "I am living in everyone's heart." Sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca (BG 15.15): "From Me there is remembrance and forgetfulness." There is . . . we sometimes forget and sometimes remember. That is by God's grace. We are practically under the . . . not exactly directly, but through His agent, the material agent.
