So in this way, if you simply study this sun . . . there are three phases: the sunlight, or sunshine; the sun globe; and then the living entities who are in the sun planet. There are living entities. Because it is impossible to go . . . you cannot go even near the sunlight, sunshi . . . globe. You cannot go even to the moon planet.
So our material knowledge, material science, our material endeavor is very, very insignificant to understand the Absolute Truth. It is almost impossible. You cannot understand even a planet, and what to speak of the Supreme. Therefore in the Śrīmad-Bhāgavatam it is said that vadanti tat tattva-vidas tattvam (SB 1.2.11). Those who are in knowledge of the Absolute Truth, they say that the Absolute Truth is realized in three phases. But they're nondual. How nondual? Just like even if you study the sunshine, it is not different from the sun, because the same quality is there. The temperature and the illumination, two main qualities, in the sunshine you'll find. And in the same way, if you study the sun globe, you'll find the same quality: light, illumination and temperature. And if you go further, if you study the living entity, you'll find the same thing: temperature and light. But there is difference still, varieties.
You cannot say . . . when the sunlight enters within your room through the window, you cannot say: "I have got the sun now. Sun is within my room." That is nonsense. No. Sun is far, far away, but his energy has entered your room. So much you can say. But if you think that because the sunlight is within the room . . . sunlight within your room? Sunlight, if it comes a few millions miles nearer this planet, it will be finished. What about your room? The temperature is so high.
