So far we get information, all the planets, they are full of living entities. Janakīrṇa. It is stated in the Vedic literatures, janakīrṇa. Janakīrṇa means congested with living entities. Therefore we see New York City is congested with so many living entities. But if you go higher, then you cannot appreciate how New York City is so congested, or other cities are congested. So similarly, we have no knowledge of these planets, but every each and every planet, millions and trillions, they are all congested, full with living entities. This is Vedic information. It is not imagination, imperfect imagination. No. It is fact. So we learn from the śāstra that on account of illumination of the moon, the vegetation in every planet is, I mean to say, flourishing condition, due to the moon. Still we find reaction of the moon on the waves of the seas and ocean. So everything has got its necessity. Parasya brahmaṇaḥ śaktir (CC Madhya 20.110). They are all acting as potency of the Supreme Lord. Parasya brahmaṇaḥ śaktir. They are śakti; they are not śaktimān or śaktimā (?). Śaktimān means one who possesses the potency. And we are all śaktis.
Caitanya Mahāprabhu is going to explain the potency of the Lord—three potencies: spiritual potency and material potency and the marginal potency. How they are acting, throughout the whole cosmic manifestation, beyond that also, that very simple word, everyone can understand. The light is here, the bulb is here, localized, but the illumination is spread. And we can take advantage of the illumination. By the sun's illumination we see practically how trees are growing their leaves, their color. Everything is due to the sunshine, we have got practical experience. Where there is no sunshine, especially in these countries, all the leaves fall down, and as soon as there is sunshine, immediately millions and trillions of leaves come out. Immediately. Not that waiting. Immediately. At least in this way you have to understand how Kṛṣṇa's potency is working. That is the Vedic information, parasya brahmaṇaḥ śaktir. Parāsya śaktir vividhaiva śrūyate svābhāvikī jñāna-bala-kriyā ca (CC Madhya 13.65, purport), (Śvetāśvatara Upaniṣad 6.8). Just like the sunshine is the potency of the sun, and how it is acting wonderfully. Everything is perfectly—the flowers, the leaves—perfectly done. Svābhāvikī jñāna-bala-kriyā ca. It doesn't require any research work how this leaf has come out. It is coming out automatically. They cannot understand. They say, "Automatically." No automatically. There is the working of the potency, but it is so perfect that svābhāvikī, as if natural, coming out. Everywhere you'll find, in your body also, potencies. You shave your head; immediately next day again coming out, again coming out. But you do not know. Let the scientist say how it is coming out, his own hair, what to speak of others. (laughter)
