Simply by Brahman realization, you cannot stay on the platform of understanding that, "I am not this body." You'll fall down again. You'll fall down again and accept this body, "Yes, I am this body." Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ (SB 10.2.32). After much meditation or hard work, you realize that you are brahma. But if you do not go further—Brahman, Paramātmā, and Bhagavān—then you'll fall down again. Again fall down. Āruhya kṛcchreṇa.
Just like, take a crude example. You have got very nice sputnik, and advertised yourself that "I have reached moon light, moon planet." But if there is no place to live, you come down again here. What we'll do? You must have some shelter. You must advertise . . . just like when I was in San Francisco—so many reporters asked my opinion, "Swāmījī, what is your opinion that they have gone to the moon planet?" I told, "It is simply waste of time." Oh, what is the use of going there and catch some sands and come back? You live there, utilize; otherwise, what is the value? What is the use of spending so much money?
Similarly, if you simply realize that, "I am brahma"—you cannot utilize the opportunity—then what is the use of realization? You'll surely fall down. Just like the man has come down again. He may advertise, "Oh, I went to moon planet." That's all right, but what you have gained? You are liv . . . you are here, like me, with me. What is your extra qualification? You are now living with me. Why did you . . . rather, I did not take so much trouble. You have taken so much trouble, and you have come back again. So what is the use of such realization if you cannot utilize it?
