I have a personal experience of Sri Krishna and have not consulted Gaudiya Vaishnava scriptures but would like to know if you agree with this conception that I have outlined:
Brahman in Hindu cosmogony and religion | Satya-advaita
Dear Shantanu:
I read your article on Brahman. Your conception is a bit different than the standard Vaishnava beliefs but shares some similarity.
Prabhupada's teachings are that Brahman is the effulgence emanating from the body of Krishna. Brahma, I think you know, is the first created living being and the creator of the material universe. I have read many Gita translations and sometimes Brahma is translated Brahman and visa-versa. They are not the same.
In the BG 8.1 Arjuna asks:
"Arjuna inquired: O my Lord, O Supreme Person, what is Brahman? What is the self? What are fruitive activities? What is this material manifestation? And what are the demigods? Please explain this to me."
Krishna responds:
"The Supreme Personality of Godhead said: The indestructible, transcendental living entity is called Brahman, and his eternal nature is called adhyätma, the self. Action pertaining to the development of the material bodies of the living entities is called karma, or fruitive activities."
Krishna says in BG 13.13:
"I shall now explain the knowable, knowing which you will taste the eternal. Brahman, the spirit, beginningless and subordinate to Me, lies beyond the cause and effect of this material world."
This differs from your conception, I think.
So we have some different definitions of Brahman. So the jiva or atma is called Brahman-his nature is self, meaning independent from Krishna and the rays from Krishna's body are also called Brahman. Therefore, as it is said that we are parts and parcels of Krishna, then we emanate from Krishna as Brahman. The first stage in spiritual realization is realizing we are Brahman, then we progress to the stage where we realize Krishna (Parambrahman, the Supreme Brahman) in our heart, then we progress to the topmost stage of realizing the Supreme Personality of Godhead, Lord Sri Krishna.
I don't know if you have read the Srimad Bhagavatam. It contains very explicit information on the creation of the universe. It is a very long work, 18,000 verses. You can download Prabhupada's original scanned books for free from Krishna.org. You can also download the Bhagavad-Gita as it is there too.
You might want to try just reading the Canto One of the Srimad Bhagavatam titled Creation. There is also some information in Canto 3 that might interest you.
There are 10 cantos on-line. There are 2 more, but were written by Prabhupada's disciples after he entered samadhi and are not offered on Krishna.org.
You can also read his books, conversations and letters on prabhupadabooks.com. There is a nice search feature so you can check the books you want to search, type the search term in the search block and check the box next to the search button to search the checked books only. Otherwise the search will look for your term in all the books, conversations, letters, etc.
In reference to your last paragraph, It is said that the demigods are the different limbs of the Supreme, so anything offered to them is actually being offered to Vishnu (Krishna). The example is given that to water a tree properly, one must water the roots, then all the leaves and branches will be satisfied. Watering the leaves and branches will not be adequate.
So by worshiping Krishna, the demigods are satisfied. No separate worship is necessary.
In BG17.14 Krishna says:
"Men in the mode of goodness worship the demigods; those in the mode of passion worship the demons; and those in the mode of ignorance worship ghosts and spirits."
So this agrees with your article.
The Vaishnava teaching is that the universe is made up of earth, water, fire air and ether. The living entities body is also made of these elements with the addition of mind, intelligence and false ego. All these elements are the inferior energy of the Supreme. The spiritual sky beyond the material creation is considered Krishna's superior energy. And the living entities are considered His marginal energy. We are considered marginal because we can be conditioned by the inferior, material energy or attain to the superior energy by devotional service. All these energies are emanations from Krishna. The energy cannot be separated from the energetic (Krishna), but is not the same as the energetic. The example is given of the sun and the sunshine. The sunshine cannot be separated from the sun, but it is not the same as the sun.
Therefore Krishna states he is the cause of all the creation, but is separate from them.
In BG9.4 Krishna says:
"By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them."
In BG9.5 Krishna states::
"And yet everything that is created does not rest in Me. Behold My mystic opulence! Although I am the maintainer of all living entities and although I am everywhere, I am not a part of this cosmic manifestation, for My Self is the very source of creation."
Krishna says in BG10.8:
"I am the source of all spiritual and material worlds. Everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts."
The Vaishnava teaching is that even though the material universes are countless, they are not infinite. After a day of Brahma they are drawn back into the body of Maha-Vishnu and after a night of Brahma creation begins again. Long, complex story, you can read the Bhagavad-Gita or the Srimad Bhagavatam for details.
Hoping your heath is good and that you are advancing in the knowledge of the Absolute.
Hare Krishna.
Yours in the service of Srila Prabhupada.
