God is the complete, eternal masculine enjoyer, containing all opulence and greatness—supremely personal, never impersonal.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Ādi-līlā 7.108 — February 18, 1967, San Francisco 670218CC-SAN FRANCISCO [43:04 Minutes] Prabhupāda: So, Brahman means "the greatest." So what is the idea of the greatest? The greatest means... That is described by Parāśara-sūtra, that He is the greatest in wealth, greatest in fame, greatest in knowledge, greatest in renunciation, greatest in beauty, everything, whatever attractive. How, how you can understand "greatest"?
"Greatest" does not mean that sky is the greatest. That is impersonal theory. But our "greatest" idea is that one who can swallow millions of sky within Himself, He is greatest. The material conception, they cannot go further. They can simply think of the greatest: the sky.
That's all. "As great as the sky." But we Vaiṣṇava, we see that Kṛṣṇa has within His mouth millions of skies. So who is greatest? Kṛṣṇa is greatest or the sky is greatest? This is the difference between the Māyāvādī philosophers.
Just like Caitanya..., Kṛṣṇa, when He was boy, He was eating clay. His mother asked, "Oh, just open Your mouth. I want to see what You are eating." And Kṛṣṇa showed him [her] that millions of planets and millions of skies are within the mouth. So He is greatest, who can show that "Millions of skies are within Me." He is greatest. That means greatest in opulence of strength..., greatest in strength, greatest in wealth, great..., everything greatest.
He is greatest. That is Caitanya Mahāprabhu's... He says Brahman means the greatest, and greatest means one who is greatest in six opulences. Now, so there are Upaniṣads. Generally they take eleven Upaniṣads primarily, but there are 108 Upaniṣads.
Sometimes the explanation is given that "Why we have got 108 beads?" "Because there are 108 Upaniṣad." So chanting of Hare Kṛṣṇa with 108 beads means that we are surpassing the study of 108 Upaniṣads. Another meaning is that there are 108 damsels who served Kṛṣṇa with all respect at Vṛndāvana. So that is also another explanation, 108. We are serving Kṛṣṇa's servitors, hundred and..., chief damsels of..., at Vṛndāvana. So these 108 Upaniṣads are described, īśa kena kaṭha praśna muṇḍa māṇḍūkyo taittirī...
You can count how many: Īśopaniṣad, Kenopaniṣad, Kaṭhopaniṣad, Praśnopaniṣad, Muṇḍakopaniṣad, Māṇḍūkyopaniṣad, Taittirīyopaniṣad. Then aitareyas ca chāndogya bṛhad-āraṇyakam tathā: then Aitareya Upaniṣad, Chāndogyopaniṣad, Bṛhad-āraṇyakopaniṣad, Brahmokaivalyopaniṣad, Jābālopaniṣad. There are so many Upaniṣad, 108 Upaniṣad. Āruṇeyopaniṣad, Garbho, Nārāyaṇo, Haṁsa. This Haṁsadūta, the name, the Haṁsa Upaniṣad, it comes from Haṁsa. Garbho nārāyaṇo haṁso bindūro nārada sikaḥ: Sika-upaniṣad, Nārada Upaniṣad. maitrayaṇi kauṣītakī bṛhaj-jābāla-tāpanīkālāgni-rudra-maitrisubālakṣari-mantrika There are so many Upaniṣad; we cannot remember them.
