Brahman is said to be amorphous in nature. Apart from the main question in the title, here is a sub-query:
Can we keep away from Brahman after seeing or realizing it?
The creative principle of the universe is called Brahma in Sanskrit. Brahma, who is depicted as emerging from the navel lotus of Narayana, is a metaphor for all of creation: its laws, its inherent intelligence, and its consciously manifested potencies which operate as sages, saints, rishis, devas, celestials, and divine beings of all kinds of nature, temperament and description. Narayana is the Sanskrit name given in the Upanishads to that which is the sum and substance of all the manifested and unmanifested realms. Narayana is that which is neither created nor destroyed but transcends the creation, life and destruction of the universe. Brahma creates, operates in the form of this universe for trillions of years, then dissolves back into Narayana. Narayana, however, is neither created nor destroyed. Later, another Brahma appears to begin the process again.
Since the term "Brahma" does not appear in the Vedas, its creation stems from the Sanskrit word "Brih" which means "'to grow" or "to expand." In this way, it became synonymous with Hiranyagharba: The Golden Egg of Creation. Growing from the Navel Lotus of Narayana, Brahma is the name for the principle which creates all of the manifest realms. Since the Vedas proclaim in the Purusha Suktam that "three quarters of this universe are in indestructible realms above," then clearly Brahma, with his finite duration, is connected to the realms of the universe which we inhabit which are subject to creation and dissolution.
Brahma was endowed with his "spouse" (Saraswati) and consciousness at the time of creation. Brahma made certain "beings" solely by the power of his mind and thought. These beings are called the mind-born sons of Brahma. The state of their consciousness is summarized by the title Brahma Rishi: Seer with the Understanding of Brahma. Brahma Rishis, in turn, can confer this state of consciousness upon others who prove themselves capable and worthy. For an example of the conferring of the state of Brahma Rishi upon one being by another, see the Story of Vishwamitra in the Chapter on the Gayatri Mantra.
To further understand the concept of Brahma and his relation to the universe as we know it, it is helpful to view the cosmos through the lens of the Vedic descriptions of the life of the universe as interpreted in human years. Here are cycles of time as recorded in the Vedas and Upanishads. Click here
Saguna and Nirgun
NIRGUNA is the eternal all-pervading and omnipresent divine consciousness. SAGUNA is the manifestation of God in form.
The sun is a graphic simile for this. Sunlight is the Nirguna form of the sun, and the celestial body is the Saguna form.
When God manifests in form he appears to be limited by his form, but his presence is unlimited and all-pervading. Nothing exists without God’s presence. God is omnipresent and absolute.
God is in everything, and everything is in God. God exists in everything that we call “good” as well as in everything we describe as “bad”. In God there is no limitation or differentiation, only unity. Nirguna God is pure energy, the living and conscious power that is at work in the Universe. Reality, the Supreme Self, is Nirguna God.
